One point to consider is the patent status of your ideas. Arithmetic 
coders are not used in the current standard because of this. And 
since software patents are usually rather broad, your algorithm may 
also fall under these patents. Ofcourse, not having looked at 
either your algorithm or the patent claims, I can't say if this is 
the case, but I figured you'd want to keep it in mind.
