Both Simple and Advanced Simple Profiles only use rectangular objects.
These are the most implemented MPEG-4 Profiles. Core is implemented
by some, including the non-rectangular objects.

Advanced Video Coding (aka as H.264) is a new MPEG-4 and ITU-T standard. 
It is surely not easier than MPEG-4 (A)SP to implement, but it will get
a lot of traction. There will be live encoding of this algorithms, and 
there will be chip(set)s for the algorithm.
