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).

(I'm not affiliated with digitalfountain in any way other than being a
customer and sharing an office with a beta tester. :))
