I don't know how far the zigflea can transmit and receive. But StickOS makes it pretty easy to connect devices that control each other. The first and I think the second video talk about hooking the remote zigflea up.

Here one piece of hardware you could use:

And pretty soon the ZigFlea should be available for it:

I don't know how much room you are left with with StickOs, but you need to get up to PIC32MX4 to use it. The chip has 512K programmable memory and 32K ram.
