That certainly would be good, he has done tremendous work for the acceptance
of internet protocols.

Some time ago I noticed that my hack in PE1CHL-NET version 950819 (Aug 19, 1995):
TCP SYN packets are examined when routed, and the MSS option will be
adjusted down to the maximum MSS possible on the incoming and outgoing
interfaces. Thus, a more optimal end-to-end MSS is chosen, and
fragmentation is avoided (e.g. when running IP over NET/ROM somewhere
inbetween the endpoints)
pre-dates the addition of this feature in e.g. Cisco routers (ip tcp adjust-mss)
by several years.... that would certainly have been patentable...

Great to hear that!
