Cool - I did exactly same thing last week, adding send/receive
functionality to the SMF service I had been playing with. More at

I've used ssh there to send/receive between servers with no problems.

Can you give more details : what's the ssh machine you're logging into
(OS and version of ssh, and perhaps the amount of encryption you're
doing). How fast is the network between the two machines ?

Does "ssh -v" tell you any more ?
