All this stuff that you're doing with the alias browser and the browser extensions/addons is great! Really adding value to the alias concept.

I think someone mentioned aliases in hostnames a few pages back, so I put together a quick proof of concept.

Try putting this in a browser:

alias.nxt.pe
or
http://alias.nxt.pe/

For example:
rasppi.nxt.pe
facebook.nxt.pe

Actually this just forwards to 22k.io/alias so it 100% relies all the hard work you've done. And it's just a proof-of-concept / something to play around with. Give it a try, and if you think it works well perhaps it could be implemented as alias.22k.io directly.
