Wireless Control

Hi. I need some suggestions. I need to control two arduinos wirelessly. I basically need to press a button on a controller and have two arduinos receive the wireless signal and react. What can I use for this? It would have to be something relatively simple to program for, and something I could get my hands on in the next few days.
Does anyone have experience with MintyMote? Would it work to have one receiver on each Arduino and one controller control both at the same time?

Thanks for your help!

What is MintyMote?

Can you post a link to its datasheet?

It should be perfectly possible to have two (or more) Arduinos receive the same wireless signal.
What are you planning to use as a transmitter? Will that be another (third) Arduino?
