How to publish a GPG key via DNS

Publishing keys is quite common. One nice way to do so is by using the Public Key Association (PKA) DNS record. Basically this is a record that points to a file that can be downloaded over the internet. This method is an alternative (not exclusive) to using keyservers. One of the problems of keyservers (in my opinion), is the problem of deleting old keys. I pretty much like the idea of PGP keyserver which verifies periodically by sending an email if the address is still in use and therefore maintain that uid of the key.
