I did this once too, s/P2P program/XML Socket Server/

It turned out that doing one in Twisted was so easy, that I never  
bothered to package another one again.  Everything else I had in  
there was more or less YAGNI because Twisted already did it, or made  
implementing the features so trivial as it wasn't worth including  
it.  These days I just whip up app-specific LineReceivers with a '\0'  
delimiter that parse/generate with ElementTree.. takes like 5 minutes.
