Mentat has a product that does this.  This isn't an endorsement of the 
product, as I've never used it, but it seems to be popular.  It does 
create split sessions (which you said you didn't want) but it is 
transparent to the sender and and receiver.  Not sure how you could 
realistically do this without splitting the connections.  There have 
also been efforts to use TCP directly but you would have to run a 
special TCP stack on both the sender and receiver.  (see rfc2760 Allman, 
et al.)
