Server side OAuth is easy to implement, even without any library: you just send login parameters and callback-url where you get actual token that can be used to authenticate user. Problem with natice client is that, well, you cannot give callback url that will always work (having http-server at client? clumsy, hotspots will block, etc.). Only way (even with OAuth2, if I recall right Google documentation) to get "working" flow with natice apps is to give special parameter as callback-url, which will return validation token in html-page. From where you need scrape it. Maybe there will be something better after OAuth2 is finished, but for now: easier to make own authentication server and API to talk with it.
