I'm with you there!  Window scaling has repeatedly screwed me over
the years because you can only set it at SYN time.  This means that
if you start something out of inetd.conf, you have to set the window
size before the app even starts (fortunately, Jason added options to
inetd to do this).  Very ugly.

Changing timestamps and window scaling on the fly would be great!
