Using VERY creative remote programming can get you around the global off issue.

A "all off" macro with the codes for each individual item, be it receivers, cd's, or Abus keypads. It simply becomes a "system off" command to the end user.

Of course Abus with a couple nice MX850's, some source equipment and you're pushing the envelope price wise anyway.

Reality is that it's just a PIA trying to do offer elaborate control for low bucks.
