Thanks.  Since I run an very secure LANphysical (it's in my home, behind 
a firewall), I'm not worried about security concerns most of the time.  
However, there are two cases I'd be interested in "solving".

1) Is there a way to use XDMCP (I use X -query) when I start my 
xterminal, such that it uses SSH for maximum security.
2) When I'm not at home, I can get to my home systems by using ssh to 
the firewall, and then ssh from their to a behind the firewall system.  
I don't suppose there's any good way (as in, without opening a complete 
hole in the firewall) to be able to run X apps on a system behind the 
firewall, with an X display that's "out in the public world (but may 
itself, be behind a firewall).

Thanks for all the help.
