When it decodes multithreaded and could be enhanced to encode multithreaded when ffmpeg starts to support this this would be a very good starting point I think.

Later it could be changed to use a more effective compression arithmetic in a higher version. But let's start small and simple. Let's start!
Maybe multihtreaded version of Michaels rangecoder could be used frame wise in a next version. But it also has to speed up a lot to be usable as an intermediate codec.
