"This project allows you to host a "private instance of S3" on top of Google's infrastructure (big table, etc), leveraging existing client S3 libraries and applications - no need to reinvent the wheel."

"You use the same Google Merchant account that App Engine debits as the one that accepts donations. This way no bank account is involved. Then you track the money that goes into the account (using the Google Merchant IPN equivalent). Then you look at your usage stats from the App Engine panel and predicate future usage trends. Then calculate the cost per month. Then divide the cash in the account by that and you have how long the service will run. You make this visible on all pages (at the bottom, say) that this service will run for X months, "Pay now to keep it running." You accept any amount, but you are completely clear about what the costs are. And this is all automated."

To use it, first, install JetPack, then, come back on that page and click on the upper-right "install" button.
You should then have a new item in your status bar (at bottom) allowing you to type your feed name and use the "add url" button to add the current url to your feed."
