On the one hand, it would be very valuable; on the other hand, the VP3 website indicates that development moved to Xiph, and Xiph Theora is incomplete and still alpha: >> Q: Can I use Theora to encode stuff right now? >> A: Yes, but we strongly, strongly recommend against it, for >> anything but test-cases.
