Aphex and myself are in theory working on this,
but truth told I've only had a cursory glance
at the source and data structures so far.

What does 'axis restricted tracking' mean exactly?
I'd certainly be glad to help you implement this stuff
(would certainly be a good exercise to learn the
constraint code -- plus I'm getting sick of auto-skinning).

OK -- how do you want to start?

P.S. I'm directing this message to the tuhopuu-devel
list which is more appropriate for this kind of
discussion than tuhopuu-cvs. The subscribe page is here:
