People are using Rendezvous, though basically they're only using it for
iTunes music sharing :) And for large organisations (eg: Apple) it
doesn't work.

The problem there is that Rendezvous is currently mDNS only. This is only a limitation of Rendezvous, which is just one implementation of Zeroconf. DNS-SD does not need to be limited to mDNS.

Apple is currently working on removing the mDNS restriction, so this problem will be gone from Rendezvous in the future. My personally guess would be in the OS X 10.4 timeframe. After that, corporate use may pick up a lot.

Zeroconf/Rendezvous is used a lot in non-corporate environments (printer, music, ichat, file sharing, etc.) already. Implementation of Zeroconf which can operate using normal DNS do exist, as well, altho they are not popular.

I'd like to see GNOME have a protocol agnostic service discovery API,
but I'm not sure how possible that is.

Yay protocol agnostic API!  :)

Depending on what we want to do with it, there's no reason for it to be hard. One does have to look at the LCD situation. Namely, is all this API going to do is allow querying for services and publishing them? Service meta-information is stored/managed differently in different protocols. One may need some kind of HAL-like library for this, so that e.g. printer meta-information can be queried/provided in a uniform fashion with the underlying library translating it to the protocol-specific formats.
