You will likely have to invent the hookup, but heyu, which was originally 
an interface to x-10 stuff, but which has been expanded over the last 20 
years to talk to other vendors things, might form the basis of what you 
want to do. Just be aware that powerline signalling isn't 100% 
dependable, and while the false positives are few, the failure to get 
the message thru needs to be handled in the scripts you'll write, 
usually by sending the command 3 times with about a 1 second time 
separation, which gets the job done with maybe 1 failure a year here.

At one point, I had ripped my music cd collection, and could take one of 
the x-10 palm pads to the basement and use it to control the music while 
playing pool with the neighbors. The palm pad was the remote control for 
xmms. What you do with it? for instance, a hawkeye or eagleeye which is 
a pir motion sensor could turn on an intercom's main power, while at the 
same time alerting you to go talk to the person at the door. Thats just 
one suggested method. And they'd not even have to push the doorbell. I'd 
think in a higher traffic situation that might generate too many 
triggers from folk just walking by, so I think I'd find a doorbell like 
button they did have to push. What you can do with it is up to your 
imagination. heyu has a mailing list, and help is there from the other 
users and the current maintainer. heyu_users@yahoogroups.com. Traffic is 
quite low most of the time.
