This seems like a really clever idea, but I didn't see any response to
it. Has anybody thought more about this?

Everything in Emacs is centered around buffers anyway and I guess that a
lot of the RPC (at least wrt. keyboards) would look a lot like the
events comming in from X anyway.

The biggest problem I see here is that you can have a large number of
buffers. I do not know what the practical limit on the number of threads
are on modern systems, but if that is a concern one could instead tie
the threads to processes/filters/sentinels (which aren't really
interactive anyway) and windows/frames which all user interaction goes
through.
