I've googled and googled and haven't found too much. Possibly the closest thing I found is that IBM is developing 100 apps for Apple as a partnership of sorts.

Developing on ASP.NET required that you had to have an Access Client installed on your machine, so I expect the same for Apple. I'm thinking of developing apps for Apple to connect to the 400, but I didn't find anything as an api call on this. Has anyone tried this before?
