I believe the OP wants to get a unique identifier for each host, 
something like a GUID. I have no idea how you would make this cross 
platform though, maybe IP address but those change, or HD serial, but 
again that's changable...

Windows supports GUIDs inherantly however AFAIK *nix systems don't.

Sorry I don't have a solution.
