Hey Joe,

Check out this badboy:

Up to 20x faster transfer than normal SSH. This would rock whether
you're doing rsync over ssh, or ssh mount, or scp, or pretty much
anything involving SSH. I haven't tried it -- I just heard about it a
few minutes ago. 

And of course, if your bottleneck turns out to be disk access at either
end, or CPU at either end, or a slow wire, this won't help you. But if
you're transferring between two robust machines connected by Gigabit
Ethernet, who knows how fast it would go!

I'm probably going to try this in the next few days.

Thanks
