OAuth and the Opera Widget Container
During the OAuth protocol exchange you basically request an authentication token from the service, and then redirect the end-user to a URL to challenge them for their credentials. This is hosted by the service, and may well have a "mobile" page for this (eg: m.tripit.com).
However, from previous experience, you might serve up a link within your mobile widget (running inside the widget container) but clicking on it will launch the native browser. The user challenge is therefore taking place inside another device application - so can you return control back to the widget to continue the OAuth protocol exchange? I'm guessing not.
Has anyone tried any OAuth authentication initiated from within a mobile widget?
