Things like this make me shiver:

Appendix A: Control Slow Start and Congestion Avoidance
Although each side has indicated the maximum size of its receive
window, it is recommended that a slow start and congestion avoidance
method be used to transmit control packets. The methods described
here are based upon the TCP congestion avoidance algorithm as
described in Section 21.6 of TCP/IP Illustrated, Volume I, by W.
Richard Stevens [STEVENS] (this algorithm is also described in
[RFC2581]).

For some reason, people really really like reinventing TCP.
I'm definitely not going to implement this, all I wanted from the very
beginning is a _simple_ way of tunneling ethernet packets. :-)
