Yeah, Thunderbird integrated oAuth in the last few releases, mainly to keep up with the Gmail and Hotmail requirements. Made it very user-friendly to set up in the GUI right within T-bird. I don't see this being a major obstacle.

I'm not sure I can imagine a scenario in production where Google would, or should, allow API access to individual gmail accounts. What's that for? So you can read all your employees' mail without running your own email server?
