- cssh stops on stdin...
  ...and hangs forever waiting for input in the clients.
  An easy way is to read from stdin and propagate the input to all nodes.
  The problem is to find a point of synchronization when all clients are actually waiting
  for the same input.
- show message when a process terminates on a node
- cssh name clash
  this is severe and we must rename our project. GNU perl based cssh project already exists
