Actually I thought you could have it in ccd/ files (et al) on the
server.  Seems I was wrong there.

There is no technical reason why one couldn't have different MSS settings
for different clients - but it comes at an implementation cost (copy
settings to the per-client context setting, etc.), which is quite likely
why it was never done.

I *do* think it is pushable (might be wrong again...) *and* since it does
not matter whether --mssfix is operating on the client or server (it will
manipulate both incoming and outgoing TCP SYN and SYN ACKs, so it is 
fully symmetric) - if you want lower limits for particular clients, it
could be pushed.

Or if I'm wrong again, put into the client config.

(--mssfix does not need to be identical on client and server, or even set
on both ends.  The lower value "wins")
