[PyMOL] PyMOL in the CAVE

Hi PyMOL users,

I would like to know if PyMOL can be used in an immersive environment, 
like the CAVE.
The only material I have been able to find is the following:

"Porting Legacy Applications to immersive virtual environments - a case 
study" by K Gruchalla, J Marbach and M Dubin.
Recently Virtalis has done some driver plugin which is very costly and I 
would like to know if there is any cheaper option.
I would just like to run a demo initially and see how the system can be 
beneficial in a CAVE.
I have also read about the Virtalis Plugin for PyMOL, but this is quite 
expensive. Does anyone know of any cheaper option of how I can use PyMOL 
in a CAVE.

Thanks
TN
