I saw this post the other day. Sun is coming out with a Java store to deliver applications. These stores are getting to be a trend! I have a “Market” for my Android phone. iPhone has the same type of thing. Linux has the repositories of packages, which though you can’t purchase programs, you can easily install programs in much the same way.
Right now, it looks like the store is just in beta. I am curious to see how this works and how it catches on.
