Ray Ozzie has added a blog entry for some work they are doing and sharing on extending RSS to enable sharing and syncing of information. I think a number of you may see that this is a updated extension of the work done to implement Groove and Lotus Notes, but done in a simple way that applications can use it the same way they use RSS. One important change here , is that since everything in RSS-SSE is done in XML it will make it the interchange of information between applications much easier than way Groove and Lotus Notes locked you into one way to do things.

Many interesting ideas there to consider for future applications. Let me know what you think.

Also here is an article in eWeek discussing the ideas here.

(Not sure how MS will make any business off this, but it looks like a reasonable way to go.)
