[atlas]DNS records for the probes' internet address

Antony, 
the "good" is for the users. It would provide them with a stable name to address the variable external IP they get from the ISP, enabling access to home machines from the outside using the name, independently of what IP the DSL modem/cable modem happens to have at any given time

For example, German DSL networks might change probe's public IP-address every day. May be as  Jo?o  suggested dyndns could work in theory. Once there are 1000s of probes what good are forward names. Then we will need hierarchies.
