[Beowulf] Pdsh output to multiple windows

I have used clusterssh many times. (should be in the ubuntu repository).

It is dependent on xwindows, as it just spawns xterms and copies the 
input stream to all the windows simultaneously. csshx on the mac works 
similarly, but with the osx terminal app instead.

It sounds like clusterssh will do what you are looking for.

Be careful how many you do, your screen can get quite cluttered once you 
get over 10 sessions going.
