I think this is an excellent start for most stuff:

The reason for all the frills is basically that some P2P protocols cheat 
and use ACK for actual transfer of data.  So I *think* both your 
examples, just try to filter only ACK's smaller than a certain size (128 
bytes is a good size), larger ones should be left alone and assumed to 
be bulk data.
