     Prehaps you should consider using wireless intercomms.  I would shy
   away from those that use the 49Mhz band or any other RF frequancy.  Some
   are available that simply plug into the wall and transmit the voice over
   your existing inhouse power lines.  These carrier-current intercoms are
   simple to install: unbox them and plug them into outlets - that's it, no
   wires to pull, no circuits to make, and they are reliable.

DISCLAIMER: I've never used any sort of intercom.
