it's interesting that you mention this, since I've worked a bit on
dummy-ups yesterday, fixing some weirdness... And I think for some
time about adding some kind of "meta" mode to allow either to
concatenate data from several units or having some magic formulas to
manage pseudo UPSs.
 driver = dummy-ups
 port = <upsname1>;<upsname2>
 mode = meta

The latter is only the current dummy-ups, with external actions as you
mentioned above (using upsrw...). This is somehow also linked to the
Powersave feature (outlet collection) management that should allow us
to stop only upsmon clients connected on a specific outlet, and which
have a shutdown level (either using a timer or level base).

More thinking needed and comments welcome...
