I have experimented with overlaying views, as well as applying a view to the skin of a model in front of the camera... So far the results are not what I am looking for, and mainly appear as a blurry ghost view... not really the effect that I was hoping for.

After some fiddling about with the above shader code and no results I took a step back and just tried to get some shaders to run, now thats working, I hope to revisit the above suggestions and try to get some better results.

I will post my findings as and when. Thanks for all the help guys.
