That's the registered name of the rpc server.
It is a gen_server, so it's not terribly difficult
to figure out how to fake a request without spawning
anything on the remote node.

Try this (not on a production node!):

{rex,RemoteNode} ! 

If you can send a message to any process on a node, you can
do evil things to that node in general.
