As always, Wikipedia has a great overview: http://en.wikipedia.org/wiki/MDNS
My interest is it's a totally simple and workable solution to name resolution in a totally ad-hoc LAN environment (think a group of laptops in the middle of the desert). Basically (if I understand correctly), to resolve an mDNS name you simply send a standard DNS request to a UDP broadcast address on the LAN. Everyone listens on that address and, if you hear someone asking for your name, you respond with your IP address. Clearly it's subject to abuse and name collisions that'd need to be addressed at a higher level, but it's an elegant solution to a really hard problem without creating a batch of new standards. Furthermore, I like the possibility of seamlessly spanning mDNS and regular DNS to have a name resolve to your internet IP address or LAN IP address, respectively, depending on whether you're on or off the internet.
