Adoption and community support are two measures that help determine whether an idea will thrive in the real world. As long as Amazon Flexible Payments Service is still in a limited private beta, it's hard to gauge success by adoption; however community support is still valid as a metric.
So Phil Burns' efforts are particularly interesting to me. Phil created a VB.NET library for FPS--something that I personally believe will be valued by the rest of the community. Experience says that VB.NET developers are highly interested in eCommerce.
As he points out in his blog posting, payments is more involved than simple "download and run". However if you are a VB.NET developer Phil has freed you from the tedium of rewriting C# code into VB.NET.
Do you know of other libraries or extensions to this service? If you do, we'd love to hear from you.
