Wow. Sounds interesting.

Adding BSD licensed code to GPL is no problem at all. It's the other
direction that's not allowed.

Yes, some patches would be great.

So, for example, that a 
    .change obj1 x=100 y=100
    .change obj2 x=200
    .change obj3 x=300 y=300
interpolates y smoothly from 100 to 300?
Interesting idea. 
I think implementing it this way will mean a lot of change to the existing
code, though, which always assumes that changes only happen between two
neighboring keyframes.
I guess you can rewrite the while(frame < allframes) loop in line 1928
so that it does the interpolation for each parameter seperately, but
it's tricky.
