On the VRPN website here it says
So it seems like there's some way to do this, so if anyone has any ideas please let me know. Thanks!//The above routines only deal with the sensor to tracker transform. The routines
//handle the tracker to room transform, unit to sensor transform, and the trackers
// workspace (working volume). These currently come from the vrpn_Tracker.cfg on
// VRPN server or client. Have this set properly on the VRPN servers allows your
// application to run on different trackers without having to change any code or
// recompile!
