A solution would be to use SecureCRT, it can tunnel X sessions. The users
will be able to send X windows back to their machines with no issues. It
does this by creating a new tty of sorts when you ssh in, basically
localhost:11 (or something like that) is set as your DISPLAY environment
variable, and that is tunnelled back through ssh. But you have to be
careful not to set your DISPLAY variable by yourself, let ssh do it.
Enjoy.
