Ah, right.  That was mentioned in the visor howto.  I guess I
assumed if there was a "hotplug" there must be a "hotunplug" and so was
looking for that.

I don't really get the design of the agent script, though.  Seems like one
would want to run a script on a hotplug (and unplug) event, not just when
the hotplug triggered a module to be loaded.  What if "visor" is compiled
into the kernel instead of as a module?  Or if two different devices
plugged in at the same time used the same module?

Thanks for the help,
