SSH Compression

[David Groos]

Hey Jeff, Sounds like you are looking for good gui remote access over ssh? I
use FreeNX as the server and use NoMachine's client and now also use OpenNX
since it works well with lion-10.7.  The access over broadband internet is
just like sitting at the computer--works great to manage remote servers
running Edubuntu/ltsp.  I hear it is even a decent experience over dial-up.
So, while I don't know what the compression is, it must be pretty good to
work this well in this situation.  If you have more questions, let me know.
David
