Ya, thats what started us off, but there are a few problems:
1) They are no longer in busniess so we can't get parts
2) There 'full source code' is actually not even 1/2 of the code needed.
3) It does not support any of the features we want
4) Is a single chip system meaning the gun is the vest, giving issues of you being invincible while firing and **** like that.

This brings be back to my main question, how can we communicate between 2 micro controlers? When one is a dedicated listener (for incoming IR) and the other is a transmitter.
Note, we will be having 2 wires going between the chips we can use, (we are using 3 but one is a simple sanity wire)
