Must be a regional thing: most of the ones I've seen around here are
dial-on-demand.

True, although if it's a "feature" then there should be a way to turn
it off.


I'm assuming through all of this that the end user wants to disconnect
their equipment from the 'net when not in use, as opposed to remaining
connected and able to collect data.  In that case, and assuming
equipment that is trying to "help" keep the connection alive, perhaps
something like the "Mini Power Minder"[1] from ThinkGeek would be of
help?  (No affiliation with any companies involved, just a "gadget
enthusiast."  ;-)
