compression and encryption with gdm, cygwin?

[Jason Pepas <j.pepas@mail.utexas.edu>]

Hi,

I am exporting a gdm X session to a windows box running cygwin/xfree86.  
is there anyway I can use ssh to make this a secure connection, and is there 
anyway I can compress the stream to speed things up a bit?  ( it is pretty 
slow as is, over a cable modem).

thanks,
jason
