Hallo!

- A python script on the master handles CAVE-specific input (such
as head tracking data) and updates the master via pdsend/pdreceive.
It may be a good idea to build a little python extension that
encapsulates the functionality of pdsend/pdreceive.

This is already implemented but not really published yet. xmlrpc was made at the IEM by Thomas Grill, which is really a comfortable interface to python. Maybe IOhannes or Thomas can give you more info when they plan to publish it?

LG Georg
