And be sure that some Real Agents won't backstab the developer =)
Universal donate project for realvideo/audio and windows media decoders would be nice.
As for RealVideo, it's not so much an issue of raising money as finding qualified developers who have both the skills and the time necessary to take on a complex project like that. If all it took was $5000 to pay someone to work on RealVideo compatibility then the money could probably be raised. But it's not that simple.
