Ok, so you can now remotely log into that box with your own X
server...

	X :1 -query remotebox

Do that, and your X server will start up, but the xdm/gdm/kdm
interface from the remote box will appear.

No, of course not... if you do it like this (with telnet), then
you'll need to set up a DISPLAY parameter that points back to the
local box, and transfer and xauth key to allow it to display.

It is a _really_ good idea to know how to do that, but the short-cut
is to use ssh for the connection rather than telnet.  Once of the
nice things about ssh is that it can do all the xauth stuff for your
automatically.

xdmcp is somewhat different to simply remotely logging into a box
with a shell.  Hopefully your experience will illustrate what these
difference are.

Have fun!
