Nice then, thanks for the info. :)

Knowing this I believe that what I was thinking of is far from impossible.
If there's demand for such a program, and there is no similar program in
development right now (maybe the IMP project will give birth to the right
thing), we could start to recruit programmers for the job :)

And if we are talking about IMP, can anyone give details about the software
they are making? How it will work, to what extent it is capable of doing
what I was thinking of (or what other pov users would expect).
I find their website confusing.
