RF link with attiny device

Using Arduino Sensors
1

Hi,guys I have these rf transmitter and receiver :

I wan't to use two separated attiny microcontrolers to send and receive numeric data.
My first question is how can I achieve this,and what attiny microcontroller to use ?
Note: I have arduino UNO and I can program any microcontroller with the ISP MODE.
What I actually want to do is to recognize when the user is around a table and do something.

No suit me,because virtualWire need faster timer0 which attiny85 don't have :smiley:
But this guy somehow managed to do it :
