Support GPS enabled boards?

I was wondering whether it was a good idea to append the node id to the self-generated nicknames created by the user? If I have deployed a bunch of nodes I may know the node ID and the location of those nodes.

So if someone logs in and says "A truck full of water just got delivered here!" and then disappears, then I can use the implied location to go and get myself a bottle of water.

I'm thinking of the code that Is used in the access point name, I think it's based on Mac address?

You could strip out the 'disaster-radio' and just use the number? So nicks would be part user-generated and part machine-generated.

eg. Bob_0F733

Is this worth doing/ difficult?
