I have added a lot of code into the SVN repository in order to provide some experimental support for Amazon FPS.

The current version (revision 186) supports most of the operations you need when you manipulate:

• single use tokens,
• recurring tokens,
• post paid tokens,
• edit tokens.

Basically the current API allow you to generate URL for the CBUI  pipelines, extract information from the request when FPS returns to your site and all the account related APIs, like Account Activity and such.

This code is still in experimental status and I’d like to gather some initial feedback.

What’s left to be done is (ETA: end of the month):

• multi use tokens support,
• prepaid tokens support,
• IPN support.
