[mythtv-users] MYthTV replacement for Intercom?

[PAUL WILLIAMSON]

I know it's crazy sounding, but can 
mythphone call other mythphones in the same house?

I have an old NuTone intercom that I'm ripping 
out, and was thinking that rather than patching 
all the station holes, I could put a small PC in them 
and an LCD panel over the hole and have myth tv 
frontends in every room.  Now if mythphone could 
somehow call another frontend locally, I'd be 
quite happy...

Should I just get out the drywall and spackling 
compound?
