Hi,

Mocap support is of course cool! :)
In reality however, not many of our users/developers will be able to  
test or purchase such systems. What would be a viable approach however  
is;

1) make sure Blender can read (standard?) mocap files from current  
systems. I've had offers for free mocap dbases in the past, still  
something we could look into. I also bet there's quite some free  
downloads for it.

2) direct mocap display in Blender could best be supported via a python  
wrapper. The Blender python API (c code) for it can be very general,  
and designed to be fast too. This also solves legal issues, since GPL  
restricts linking to non-GPL libraries/software.

Approach 2 would probably require to design a special mocap python  
module in Blender. Which could have part of the functionality of the  
provided c code. Would also help if someone can assist on that work who  
has knowledge how to support multiple mocap systems.
