I must say here that proposed MPEG-LA licensing terms are still not final, and probably will change in months to come, before the official launch of the MPEG-4 visual licensing agreement!
This level of confindentiality is very interesting - for example, couple of days after MPEG-LA announced licensing plans, my company licensed MPEG-4 video codec to one distance-learning company, and the biggest issue was this "per-view" fee, VP of sales of that company made some phone calls, with Larry Horn from MPEG-LA, and decided to go with MPEG-4 - probably because of one year grace period that will be allowed to MPEG-4 visual licensees.
For interested people, there is an ongoing hot debate on M4IF "discuss" mailing list, which is open to public - there are very important opinions of key-people, like Yuval Fischer from Envivio. I must say that most of them are against this way of licensing, and I sincerely hope MPEG-LA will withdraw it from the final agreement. The fact that Apple (one of the MPEG-4 patent holders) is against this way of licensing is very encouraging - their opinion certainly counts ;-)
I've also heard rumours that some companies inside the patent pool wish to slow-down or totally destroy MPEG-4 adoption with this ridiculous licensing plan, because they have their own technologies (guess who
Also, MPEG-4 Audio patent group (M4Audio-LC) is also working towards joint licensing for MPEG-4 audio - but from what I hear there are some problems inside the group which will postpone the final agreement.
