Not sent an appliacation yet but I will do once it gets on its feet. You can find out more information at http://www.services.Google.com/payperaction
It hasn't been released yet to the GP. I think they are still trying to iron out the bugs and maybe look into how a certain other PPA network is doing so well. I sent in my app a couple weeks ago and haven't heard anything yet.
Just a correction to the above post, the link is actually: http://services.google.com/payperaction/ Zach
