I just found GAE and I am very impressed so far 
I am just curious, have any of you integrated (from applet or application) ingame user login with google accounts? Is it even a good idea?
I asked this just recently ( http://www.java-gaming.org/index.php/topic,22150.0.html ) and the overwhelming response seemed to be that people didnāt want to type the google login details into a random 3rd party game/app (which is fair enough, even if itās heavily sandboxed and restricted).
Roll-your-own seems to be the way to go (although I do use googleās login for access to the admin pages, because thereās only really me thatāll use that and it saved me some implementation time).
What about Single sign on? Is it possible to use it from a client app?
I never minded that, but only used it in a browser. Probably people that donāt understand it will balk at having to sign on google thinking iām trying to capture their credentials.
