just to make few points clear for the person who asked you and  those
who just read list and are not motion capture experts
and for myself ;)


there are many standards to describe motion capture data see
http://en.wikipedia.org/wiki/List_of_motion_and_gesture_file_formats,

and nite motion data from kinect  is a variant of processed motion
capture  data  - it is what is used in Kinect related software,
but it has hardly anything to do with any of mentioned standards ( so
to turn it into bhv format requires additional processing step but in
the end kinect data cant  be turned to standard bvh file, as we know
from several ready examples) .

so nite joints and skeleton  could  to a degree be portable with other
software - as at the end it is all about joints and skeletons , but
not necessary it will happen automatically (skeleton can be coded in
number of ways - which I oberved in several free bhv  viewers - there
are few on the net and each uses their own approach to represent
skeleton ), thus if the code is done with the idea in mind that it
could be portable - it is great.

as really - if one captures joints and skeleton - it is what any
motion capture software should output in the end
and thus to degree could be compatible with software you are about to develop.

to test how it goes in sense of portability,
I already mentioned one  project

http://code.google.com/p/openmocap/

see description of whole idea behind the project (in Portuguese) ( yes
I do not know Portuguese, no I expect many on a list do,
but I managed to read the doc with the help of google translate as the
text is selectable and actually understood it...)

http://www.bibliotecadigital.ufmg.br/dspace/bitstream/1843/SLSS-7WMJG9/1/davidlunardiflam.pdf

( brief description in english is here
http://www.sbgames.org/papers/sbgames09/computing/full/cp20_09.pdf ,
and one more doc can be useful too
http://www.riyazassrafally.com/personal/cd/dissertation.pdf )

so if at some step you could try how the software could be combined (
in a hackish way ( not ready for artist use, but as proof of concept )
that should not be too hard ) that will be great.

Regards
Sergey
