Quick "support us" page for donations towards an Azure account
Provide a simple "Donate Now" page for Azure accounts (or only specific account services) that shows:
--Current Account Balance
--Estimated Current Monthly Charge
--Form for donating via credit card towards the account's balance
This would be a huge boon for non-profits and community supported projects. For example, azure-websites could have a "Keep this site alive" link... or server-dependent indie games could direct users to a "Keep the servers up" page...
Our billing APIs might help with your scenario. You can use our APIs to get your usage data, and then combine it with the results from the rate card API to determine your costs.
