I can sync calendars without any problems, but I do not even have read access to tasks...
Web Applications Stack Exchange is a question and answer site for power users of web applications. It only takes a minute to sign up.

Many developers want such an API, so such functionality will probably be added soon.
Until then, there's not much you can do. Sorry!
