MobileMe needs authentication to do WebDAV, so you would have to give the other team members the username and password, which might not be desirable (if you used the email part of the service, for example). I would make an account on the Omni server for collaboration purposes, and hand out the username and password to the team. Alternatively, it is about 10 minutes of work to set up your own WebDAV server on a Mac, though it gets a bit trickier if you need it to be available from outside your network. Or yet another approach would be a Dropbox/DropDAV account for the team to use. Common thread is that there's an account on a server that everyone can access.
