I agree. Example.com should be default be interpreted as a first class identifier.

The main issue here is who owns the naming registry. Under what circumstances does a name change control? The ICANN infrastructure is cumbersome but essential. Trying to replicate the DNS and ignoring the needs that led to the creation of ICANN is doomed. Trying to establish a proprietary registry is the sort of dotcom nonsense everyone apart from O'Riely and his Web 2.0 types have grown out of by now.

OK call it an RFC 822 format address then.

On the contrary there is a very high degree of probability that they are the same.
