I didn't mean to imply the physical layer was exclusive.  However one of
the 'selling' points of CeBus was that it would 'join' the physical
layers with a common protocol/architecture. That was my point.

TO this day one of Home Automation's problems is the continued lack of
industry wide standards for various phsyical layers.  CeBus tried to
fill this void, but it went WAY overboard to try and please everyone.
X-10 is a 'standard' I guess, but it is lacking.  RS-485 sure could use
a control and protocol standard.  Ethernet is making a splash in HA, but
it too needs soem type of standard as well (ports, protocol over
sockets, etc)

A few have tried to support as many modules as possible (Commander-X)
but its difficult to do and standards would make that a lot easier.  But
vendors see standards and think loss of monopoly in that once they sell
a controller, the user has to buy their add ons.  Th eproblem is not
every company has every type of add on - so often it would be nice to
buy fro9m another vendor.

But I digress ;)

| So can any protocol.  The physical layer choices aren't exclusive to
CeBus.
