Posting this note from barnabywalters.bit — been experimenting with namecoin, got .bit domains resolving on my machine by following instructions namecoin.bitcoin-contact.org, installed namecoin wallet on my VPS and registered a name, pointed it at my web server.
Surprisingly it was a fairly straightforward process. The most difficult part was getting hold of some namecoin to register names with — I ended up trading some of my DOGE for NMC on vircurex.com.
