Brilliant. They'd get my upvote that's for sure.

I don't know much about namecoin, so forgive me if this is a naive question: could this also be extended to MX records? Creating a translation layer that somehow allowed someone to send an email to [email protected] and have it actually route to me would be amazing.

The argument could be made that we don't even need this once private messaging is released, but being able to somehow use the email protocol would surely increase ease of adoption.
