Avatars don't occupy a common coordinate-space, however. All we

avatar itself (AFAIK) exists in its own independent coordinate-
space, sans reference to the common coordinate-space in which other
agents are positioned, and with even less relation to the coordinate-
spaces of other avatars.
But in the viewer the avatar shares a coordinate space with the world.
Flexible prims attached to the avatar object global forces, not local
ones. Particles from prims attached to the avatar obey a global
coordinate space and can target prims attached to other avatars.
That's the coordinate space this hypothetical "IK tweaking call" would
operate in.
But that's all very dependent on the viewer, which is a wee bit less
than deterministic - so it would be plesiokinematic, basically? Everyone
would see something different, but that's okay so long as they also see
something similar?
