Twitter single-sign-on for iPhone?
The Facebook app has a really nice "single-sign-on" feature that uses URLs to send authentication requests to the Facebook app (where the user is normally already logged in).

Is there a similar functionality for Twitter? Most Twitter libraries I've evaluated uses a web browser, but they don't seem to keep the session, and the user has to enter the password every time.
