First of all, congratulations for the opportinity - even though I don't know you, getting an offer from Google is a rather rare thing in the IT sector.
However the reason I'm writing is because recently I started developing OpenSocial as in Hungary the biggest social networking site implemented OS support 1 month ago. I would be interested in your award winning application. I would be happy if I could get in touch with you.
Cheers,
Gergely
