			** oggenc2 is a fork of xiph.org oggenc available for the Win32 platform. Sources are available under the GPL. Unfortunately it does not compile under POSIX systems. Oggenc2 has a lot of features and bug fixes over xiph.org oggenc, e.g.:
			*** use of libsamplerate for resampling, giving a higher quality;
			*** support of 32 bit and floating point WAV format for input;
			** this project should port all the improvements in oggenc2 to oggenc. Note that the two projects are diverged somewhat and so oggenc may have some other features that oggenc2 have not, so a straight port of oggenc2 to POSIX could not be the right approach. The best way is to get the source of all versions of oggenc2, do a diff between them and try to apply in oggenc.

	Proposed Development: SHARE is intended to be a PHP project. We do not discard the possibility of using Rails or Python, but the current SOM server does not support these. SHARE will be a WebJay-like clone, as in users will be able to register, vote, comment and upload their own XSPF playlists. Basically, it is a playlist sharing application. Using OpenID for registration and Cortado (an existing Java applet) for playback would be welcome additions.		Proposed Development: SHARE is intended to be a PHP project.

			=== Cross-platform Xiph encoder wrapper in qt4 ===

			Mentor: Not specified yet<br/>
			Existing Feature Set: qt4 is a cross-platform C++ widget toolkit, which makes it easy to create GUI programs. Xiph has encoders for all of its main formats, but they are command line only, which a big no-no for the average user.

			Proposed Development: The idea is to create a qt4 wrapper around those encoders to make it easier for anyone to encode media into Vorbis, Speex, Theora and FLAC. This would likely boost the popularity of said formats tremendously.
