Andy Connolly gave a talk on the current status of their NASA AIRSP funded project for creating, federating and sharing simple "gadgets" or "widgets" for accessing online resources and performing basic data manipulation and visualization. Entitled "AStronomical COllaborative Toolkit" or ASCOT, the long term goal appears to be a "collaborative" framework for sharing the suite of gadgets and a user's associated data analysis steps with others. Andy told us that "sharing" was the next step in their efforts.
Referring to this as an "iGoogle" model for astronomy research really doesn't capture Andy's project, because the expressed purpose of such a research website is having the gadgets talk to one another and share data derived in different ways. On iGoogle, having your Gmail widget talking to a Facebook or Farmville widget would be a really, really bad thing.
