Yes, I'm using xAP. There is no "universal" standard for this
kind of
thing -- that's why we invented xAP :-)
Comfort is now xAP enabled.

I use: RS232, 485 and Ethernet. Ethernet is favourite, but bumps up
the cost significantly. For simple activities I use PIC's with a
serial interface, and daisy chain them off an Ethernet enabled
controller. All the comms - serial and ethernet - is xAP compliant.

Hub based architecture which is also 802.11b/Bluetooth friendly is my
personal preference.

I think there is interest... most of us have only just begun to
explore the possibilities offered by "pervasive connectivity"
between
devices (and I think my HA setup is reasonably cutting edge...)
