Radio remote - especially energency stop

Hi guys,
I am trying to design a remote control probably on 400 MHz range, as I think will be enough for the data I want to send.
8 channels, solid state transistor outputs.
The thing is that I never used radio modules before. I was looking at the Microchip RF modules, but I don't know exactly what to do if I have more devices transmitting on the same channel or so. What advice would you have in this way for me? Would using a PIC and coding and decoding the message be enough?
What do I need to have in mind if the surrounding area will be full of electromagnetic waves? (industrial noise)
About an emergency stop button - what algorithm or what way of designing the remote would one use for that?
Thank you.

Reliable emergency stop operation may require a permanent link (secured by a code) that asserts the stop condition also in
case of link failure.
