Also witness the BGP data/keepalive mechanism. Messages are sent at least every <x so often>, and frequently contain data (or at least a keepalive instead of data). If ACKs were sent in the same way, and packet fragments could be passed to the application layer before all segments were received in order to alleviate mbuf issues... UDP, anyone?
The folks over at digitalfountain have a pretty spiffy product that does kind of a UDP encapsulation between their end points (TCP -> df box -> UDP -> df box -> TCP) which works quite well for fast transfers over high latency links (satellite, etc.). Also lets you get the most out of your available pipes (i.e. 95% utilization of a DS-3 vs. a much lower figure using TCP to transfer the same amount of data).
