Its a very good question.
There is a lame 10 party limit on the AccuVote that has existed for as many years. Its a hard coded thing that can't be fixed without a memory card format change.
We are however in the middle of 1.96.3 testing. We can't make it dynamic without major surgery, but Its trivial to bump the limit from 10 to 32. We'll make it so for 1.96.3-final.
