My point is that today we must have such a correspondence, but
I'd like to get away from it.  The most likely scenario for
a machine with a mouse is that all mice connected to it should
be "in parallel", i.e., should appear as one "device".

If we want to put this functionality in the kernel or in X
is another matter.

Using an ioctl() to control it is certainly one way.
Maybe just a /dev/wms which just unconditionally joins all /dev/wmsN
not otherwise opened is a simple solution.
If we want it in the kernel at all.
