It seems that here is an opportunity for namecoin to make itself useful for bitcoin and gain wider adoption. What do you think?
The alias feature is mentioned in the
BIP 0015 and has been discussed on the bitcoin development mailing list.
I think Namecoin is the perfect solution for aliases because it relies on no external server (no dns server, no forced external service, etc), benefits from the blockchain advantages and would be very easy to add into bitcoin.
PS : BIP 0015 page is locked, so it's not possible so add Namecoin to the list.
But here is the the summary :
