And Zeroconf will do the same for IP.

Or, the people running the building's network have decided, quite sensibly,
to not allow random machines on their network. Bandwidth use costs $$$ you
know. Have you talked to the IT people about this yet?

On the contrary, it works brilliantly. The entire net runs on it.

IP is quite simple, in some ways too simple. It doesn't have the services
that you are used to with Appletalk, which is why it's harder to configure
sometimes. But it scales really well, (to interplanetary levels in
fact...there have been IP networks set up between here and Mars.), and is
able to handle a lot of different uses.

All protocols are stable. The only thing that makes a network protocol
unstable is the hardware.

Yep. And don't assume that just because you can't connect from a building,
that there's 'something wrong'. In fact, that means there's 'something
right', as the security setup is preventing unauthorized hosts from eating
bandwidth.
