The only one that has bitten me so far is 5 (for audio, not control, I
like unbounded control ranges). 3 would have been nicer I guess, and 4
might be a problem when I try to do stuff in realtime. But I think they
were all worthwile sacrifices for the S.

Definatly, there is a need for a non S GPL'd plugin API. And The work that
has been done on MAIA sounds great.
