ah I never knew that the protocols behind the zeroconf services (Bonjour etc.) can also resolve hostnames. Very interesting. Although I have to say that in my experience these things are not robust enough yet. Setting up the printer at work was a pain because it was not automatically found (okay, this is a complex network) and at home I have a few devices that should talk with each other (some running behind switches) but only if I start them in the right order.

I wonder why there's no way to let the router handle the DNS with some sort of registering/de-registering functionality? I would think this to be more robust compared to the broadcasting.
