grep who for the 'FROM' parameter, I suppose. Depends - do you want to be 
able to get name 'A' when logged into 'C' via 'B'?

My ssh isn't linked with X - I thought it just tunneled a standard 
connection? I suppose it depends how it sets up the connection - it could 
always ldload - I've never had ssh on a machine without X. 

I can think of one evil way. Run dynamic dns. On your X machine, make it set 
xhost.localdomain (or whatever) on the named to its local IP. Then, in your 
login scripts, set DISPLAY=xhost.localdomain:0.0 (assuming you don't have 
anything fancy on the X terminal).

*ugh

Cheers,

Alex.
