OK, here's how I'd do it:

 - Define a virtual machine with a bunch of instructions specific to
what you want to do (e.g. 3D modelling primitives, gestures, or
whatever)
 - Make the instructions serialisable
 - Squirt instructions across the network to communicate between machines

This is kinda special case of serialising continuations, so you might
be able to leverage the web server's support for this to get this
project going in a hurry.

All up it would be relatively simple to get a prototype of this going.
Perhaps a day's work? There is good support in PLT for restricting
evaluation (e.g. the sandbox) so you would be able to reuse large
parts of the PLT runtime and not worry about security etc.
