I should point out that the collaboration via Python is
not the same as using a RemoteSlaveDisplayImpl, as demonstrated
in Test64.java and Test63.java. Collaboration sends the Data
between machines, while the RemoteSlaveDisplayImpl logic sends
image snapshots between machines (not BufferedImages, since
they are not Serializable).
Of course, if the Python collaboration serves your needs
it is amazingly easy to use.
