	We want to add support for Google's Chrome OS. As a base, libvlccore, VLC's cross-platform compatibility core needs to be adapted to add support for Chrome OS' NaCl runtime environment. A base was laid internally last fall, but it is far from being complete. As time allows, this project should be expanded to add video and audio output modules for this platform as well as a basic, HTML-driven UI to test.		We want to add support for Google's Chrome OS.

			=== XML fast and small implementation ===

			The goal of this project is to write a new XML backend, based on a smaller library than the full libxml2. Speed would be nice, but code size matters here. Beware: we need to have a stream-XML based API, not a DOM one.

			This project requires good knowledge of C.
