I think that could work pretty well for mice.  A little complication
in the daemon is that it has to watch for new mice being connected
(and possibly create new device node if you run out).

I think a harder to do this way are keyboards.  I'm not sure
how to persuade X to use a multiplexor for the terminal and
get it to work.  But I've not looked into the keyboard issue
much yet.
