I have been working with ways to get Internet services to talk to Smart Phones. Initially I plan on doing DRUPAL to iPhone. But I am also experimenting with Google AppEngine to iPhone.
As I see it, these are the requirements.
On the DRUPAL SIDE:
- VIEWS module integration.
- Some kind of Authentication not just LOGIN but also Authenticated seccions to secure data pages.
- Way to Submit Data to the DRUPAL site.
On the iPhone
