If I was talking about a complete procedural animation from scratch,  
sure, but I'm not. I'm talking about using IK to tweak a canned  
animation slightly to adjust for differences between avatars.

It'd all be done in the client. The canned animation would play and  
when the prims running the tweak got into a certain range of each  
other they'd get pulled gently together like magnets in jello. The two  
different clients might not see the same things happening at quite the  
same time, but that's already true for canned animations.
