Actually, I can see the beauty of name-to-dynamic-IP-tracking, but I
doubt that it is a reasonable investment to teach the small things to do
dynamic DNS *centrally*.

To be able to get a grip on that one, I think we'd need to better understand
when and how the probe detects an change of address?

My feeling is that tracking of IP to name mapping is a local issue.

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.
