Almost a whole day since the last update ! High time for something
new:

http://www.almesberger.net/tcpcp/tcpcp-3.tar.gz

The main change this time is that restarting the connection is no 
longer done by setting TCP_ICI, but by setting the new socket 
option TCP_KICK. This avoids the "need to reconfigure firewall 
within RTT or performance may suffer" race for applications.

So this leaves mainly the difficult parts (OOO recovery and
urgent data) to implement/fix.
