Skeleton tracking without calibration (psi pose)

I would like some information on this subject also. I currently have a project where I am using Quartz Composer, VDMX, Ableton Live, Synapse and TouchOSC. The project is going to be run in 2 weeks and I need to figure out a way to abolish the 'Psi' calibration pose as it is going to be running in a theatre on a large cinema screen.

I would love to hear if anybody has any suggestions or workarounds for this. I do not use openFrameworks yet but I will be studying it this september as part of my MA/MSc.

Thanks for any help.
