Brian, derek, thanks for replying. I know you guys can't keep on top of everything. I chose the forum over email just because I thought users might be able to help me straightaway. I don't mind bumping a post to give it a second chance to be seen.

So I'm likely correct in guessing that something about the wifi network at work is blocking bonjour. I will talk to my own support ninjas and see what can be done. It's quite possible they will be able to help me with a WebDAV server. Or I can get MobileMe and charge it to work.
