Baby monitors suck.  Despite claiming to be "digital" and using the 2.4GHz frequency range, they don't actually seem to use spread spectrum radio technology.  As a result you get terrible interference if you live anywhere with lots of radio noise, like say a modern suburb under the flight path.

I've got Cat6 running from the baby's room, and I can easily patch it through to the Cat6 in our lounge room.  So could I rig up something to act as a baby monitor that way?  Thoughts?
