Change terminal an application is connected to/running on

Anyone know?

Lets take something simple like top for example. It's running on another
machine under another user. You log in on this machine, and want to see what
it's doing. How do you redirect it's output terminal to yours?

Also, for xwindows. Can you modify the server/display at runtime?

Also, is there a way to use VNC to view a running session, instead of
starting a new one?

Sorry, I know this isn't strictly the right newsgroup!

Thanks!

redirect stdout to the other pty/tty:
top > /dev/tty<x>

get the tty's by running `who'
get yours by running `tty'

don't know if I get you but:

DISPLAY=<IP>:<display>.<display>
export DISPLAY

...sets the variable (within the currenet shell)
