GNU screen can do this. You can use the command :screen ssh host and it
will spawn ssh instead of a shell. You can also add these type of
commands to your .screenrc so you can spawn N number of connections on
screen startup.

If you want help with screen (or setting up the above), there's the
gnu-screen at yahoogroups.com mailing list.

GNU screen can probably also handle doing this, though not in the
multiple xterms GUI kind of way you ask. You could have 1 screen session
in an xterm and change your current screen window to one titled "foo"
with some scriptage.

As far as GUI stuff goes, this would probably best be done at the window
manager level. I'm sure one could make this work with some LISP if you
used sawfish as the window manager and set the window titles on the
xterm.
