I ran across the Microsoft Simple Sharing Extensions Specification today and am quite excited by it, especially for enabling loosely-cooperating apps to use RSS as a way to share data/items in a list.  I'd be quite interested in other ideas on how it could be used with scientific data/research.

What is the Simple Sharing Extensions specification?

Simple Sharing Extensions (SSE) is a specification that extends RSS from unidirectional to bidirectional information flows.

SSE defines the minimum extensions necessary to enable loosely cooperating applications to use RSS as the basis for item sharing—that is, the bidirectional, asynchronous replication of new and changed items among two or more cross-subscribed feeds.

For example, SSE could be used to share your work calendar with your spouse. If your calendar were published to an SSE feed, changes to your work calendar could be replicated to your spouse's calendar, and vice versa. As a result, your spouse could see your work schedule and add new appointments, such as a parent-teacher meeting at the school, or a doctor's appointment.

SSE allows you to replicate any set of independent items (for example, calendar entries, lists of contacts, list of favorites, blogrolls) using simple RSS semantics. If you can publish your data as an RSS feed, the simple addition of SSE will allow you to replicate your data to any other application that implements the SSE specification.
