well, as i said, the two things, encoding and packetizing are very 
different things and shouldn't be in the same module. detecting when a 
packet is recieved can be simple or complex and can require a lot of 
buffering and solid i/o coding. that has nothing to do with an 
encode/decode module. adding cruft like that is what can ruin a good 
module. keep it simple, stupid! :)

thanx,
