ive one little request if you "invent" a h264 with range coder and that is
that it should be losslessly transcodeable to standard h264 (=so only the
CABAC coder would be replaced by our range coder without any other funny
changes) that way such non standard files could always be converted lossless
to standard h264 files

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
