	Since NetMD devices still kept the old MiniDisc format, it is not possible to transfer audio data to the device without additional software. On Windows, this is achieved with the infamous software SonicStage [http://en.wikipedia.org/wiki/SonicStage]. Naturally, this software was released for Windows only and development has ceased around 2007 with version 4.3 (4.4 in Japan). People who want to continue using their NetMD equipment are thus stuck using a compatible version of Windows. Since SonicStage uses a lot of dirty hacks (it has to be run as Administrator for full access to the Windows registry) and the NetMD devices require special drivers, the list of compatible Windows versions is quite narrow, namely 32-bits only. Naturally, Linux and MacOS aren't supported at all.		Since NetMD devices still kept the old MiniDisc format, it is not possible to transfer audio data to the device without additional software.

	A project on Sourceforge called ''libnetmd'' [http://sourceforge.net/projects/libnetmd/], was started in 2004 to start developing a free implementation of the NetMD protocol. Since the NetMD protocol is based on a standard (AV/C-over-USB), the protocol can be implemented right a away. However, libnetmd always suffered from the fact, that ~~all~~ transfers to the NetMD devices are encrypted. The original libnetmd therefore never allowed to transfer any tracks to the devices. However, the implementation allowed things like renaming tracks or remote-controlling the NetMD devices.

	While the upload code works unencrypted and thus without the need of any encryption keys, downloads are encrypted and require the data to be encrypted with a key accepted by the NetMD device. Since the keys are proprietary secrets of Sony Corp., we cannot use the original keys for the encryption. Luckily, the keys accepted by the NetMD hardware for an encrypted transfer can be calculated dynamically. In fact, the root key used by the ''downloadhack.py'' was encrypted with the help of a secret Sony master key. However, it is not necessary to know the secret Sony key, but it is enough to use the key that is already provided by ''downloadhack.py''. Since we created this key ourselves, we do not have to fear any issues regarding copyright infringement of proprietary code and/or information from Sony Corp.

However, many parts of the code are highly experimental even though they work and most average users prefer easy-to-use GUI-based software, which will run on their platform of choice.

Eventually, both HiMD and NetMD will be readily available from the linux-minidisc project and can be easily adopted to software applications like VLC and other free media players.

	Since there is already a C library for NetMD available ([http://sourceforge.net/projects/libnetmd/]), it would be good idea to use this as a basis for a new implementation instead reinventing the wheel. This old implementation already allows renaming, moving, deleting tracks and so on (see [http://libnetmd.sourceforge.net/]) but lacks the capabilities to transfer tracks "to the device" (in Sony terminology this is referred to as download) and to transfer tracks "from the device" (Sony calls this ""upload""; upload is supported by the MZ-RH1/200 devices ""only"").

This old implementation already allows renaming, moving, deleting tracks and so on (see [http://libnetmd.sourceforge.net/]) but lacks the capabilities to transfer tracks ''to the device'' (in Sony terminology this is referred to as '''download''') and to transfer tracks ''from the device'' (Sony calls this '''upload'''; upload is supported by the MZ-RH1/200 devices '''only''').

	Considering the old ""libnetmd"" is used as a basis, the first step would be to import the source code of this library into the git repository of ""linux-minidisc"". Then, since the library has already been without maintenance since 2004, the second step would be compiling the library on a current Linux installation and fix any compiler issues that might arise. After the library has been verified to work in a current environment, it should be tested to work with Sony's MZ-RH1 MiniDisc Walkman (the latest and also last MiniDisc device available) and any problems that might arise should be patched.

	After the previous rejuvenation steps, ""libnetmd"" is now ready to be extended with download and upload capabilities (note the terms mentioned above), with the help of the PythonNetMD code [https://wiki.physik.fu-berlin.de/linux-minidisc/doku.php?id=netmdpython] which serves as sample code for an implementation of both download and upload capabilities (see above summary of the Python scripts available). Since there is with the MZ-RH1 (the MZ-RH200 is a RH1 with different accessoires shipped) essentially only one MiniDisc model available which supports uploads, it's preferred to work on the implementation of the download code first.
