  I would like to take this a step further.

  Let's say I've started 20 xterms, each with an ssh session to a
(different) host. Can I bring one of these xterms to the foreground
by hostname?  

  E.g. I have xterm/ssh sessions to hosts: apple, banana, orange,
and tomato. :)  I'd like to run an app that will make a small window
pop up, I type "apple", (or "a", and have a name completion routine
fill out the rest), hit Enter, and voila, the xterm with the ssh
session to "apple" is brought from background or iconization to

  With 30 different xterms open, this would be VERY handy.

  Has anybody else run into this already/solved it?

Best regards,
