I'm not against this, but I think its way overcomplicated when compared
to the DNS or HTTPS methods.

OK, not too debatable, but considering how terrible bitcoind's account
handling is, the second might not be easy to get right...

This is where I think this method becomes way overcomplicated. Not only
do you have to update the IP-Transaction code, but now you have to
implement the full DNS System that is the other option as well. Note
that to make this secure, we have to have a full DNSSEC-capable resolver
built-into bitcoind (there are libs, but it has to happen). Yes you can
ask the user "does this fingerprint look right to you? Y/N" but that
always opens you up to a ton of users getting screwed out of coins and I
don't think it should be enabled, except in bitcoind, and since the main
target of this whole alias system is bitcoin-qt users, well...
