It assumes various things:
- ssh user@remote succeeds without a password
- network device to use is em2 (otherwise, change the config)
- it assumes it is run from the build directory (actually, it verifies this)
- it assumes ThroughputPublisher can be found in exactly the same place on the remote
- probably some other things as well ... use with care.
