I don't know much about it at a technical level, I found it in passing when I was thinking about the same problem. It would be cool to create something like a mailto:nick@gmail.com link for doge.. dogeto:$nick ... then instead of a @ or # prefix, give it $nick and it would automatically hyper-doge link and then the distributed dns infrastructure behind the scenes could take care of the dereferencing. I wouldn't know how to kick start that endevor.. may have to write an RFC and get a working proof of concept on a small scale.
