I think it's better to have two different programmers. So it's easier to 
maintain the code. The protocoll is totaly different so that we would 
have a big if-condition in every function to decide which one should be 
used. It's IMHO a better way to split up in two different programmers.

I agree that this could lead to confusion when someone would like to use 
the stk500 programmer for protocoll 2.0 but maybe there can be check 
within the old stk500 code to see if it is a v2.0 programmer and it 
could print out a message.
