From their Associates message board: "We wanted to let you know that on Monday evening (9/30) we are planning to launch a beta version of Amazon.com Web Services 2.0. We will be following up with more details of this launch next week, including how you can participate in the beta, but right now we just wanted to apprise you of the changes that are coming."
Regarding the comments I made about their compensation structure, they’ve been listening and a new system is on trial for Q4. I they’re persistent in their technical and commercial efforts, they might build a strong competitive advantage through an online channel that no other site I know of is even trying to build.
