These wireless transmitters work with our 434MHz receivers. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.

This comment is more to say how good proto-pic are on the delivery. Ordered at 11pm on a friday and received it the next day. I might have been lucky with the post but they always delivered on time or earlier and well packaged.
On the product side, it's small, easy to setup (just 4 pins) and has got a good range even through walls.
I bought it to use with Maplin remote plugs. Using this amazingly easy to implement code from here: http://www.fanjita.org/serendipity/archives/53-Interfacing-with-radio-controlled-mains-sockets-part-2.html
