Google Alternative To ‘DSH’ ?

Looks like Mikal and Andrew have come up with an interesting take on the age-old cluster/distributed SSH tool, like LLNL’s good old pdsh. But the twist is this (from their FAQ):

You run a utility (cssh) giving a couple of server names as parameters, and then xterms opens up to each server with an extra “console” window. Anything typed into the console is replicated into each server window (so you can edit the same file on N machines at the same time).

It should work on any POSIX system (including, they claim, CygWin).
