As I see it, in WO, I can either choose between a Java Client application, or a Web application which is accessed through a web browser.

Additional you can use WebServices to communicate with a Cocoa application. Be prepared to have a lot of traffic between the app and the server when you have long lists or big objects. Also you will run into a good bunch of optimistic looking failures when a couple of users work on the same data.

Perhaps AJAX may a not soo bad idea to get the interactivity to the user and the direct connection to the server.

It all depends on your problem and the typical usage patterns. I have learned in the past that users are happy with a simple web interface if it works as expected.

Or, to put it in other words: I've read that WO is the technology behind the iTunes Music Store. The iTunes application itself is pure Cocoa, I guess. But what is actually connecting the two?

XML. Not sure whether it's a WebService (SOAP).

Keep in mind: asynchronous work on shared data by a couple of users on large dataset and a Cocoa app displaying/editing the data will:

- give you HEAVY network traffic,
- drive you into a lot of locking handling,
- makes the whole dev process much more complex,
- make you mad because you have to handle a lot of WebObjects AND a lot of Cocoa problems.
