XBee's run a self-organizing mesh network protocol stack, 
using what sort of looks like 802.11 wireless networking (but 
is a different sub-prococol) radio as a 'physical layer'

Between two connected units, the data stream looks like a 
simple serial stream.  The connection can actually be more 
than one to one, and there are sub-addressing capabilities
see generally this third-party site -- Digi (XBee is their 
brand trademark) and some others being the primary suppliers:

This is heavily commented one way code (one sender to one 
receiver, with no curcuit 'turn-around' logic)

There are maximum voltage limits on the little devices, so I 
suppose it is possible one could be burned out with an 
inadvertent 'wiring up' error

and as I recall they have 'closer' pin spacing than the 10 per 
inch which the standard nylon breadboarding strip uses

Here in town, MicroCenter shows an interesting 'carrier' that 
will drop on top of an Arduino for cheap:

to get rid of physical layer issues ... three shown in stock

and I assume, but I cannot coax their search interface to see 
about the radio units
