I had a skype video chat with Karime Chine and he was kind enough to walk me through the new portal Elastic-R at http://www.elastic-r.org

Basically you can work on a collaborative basis in this with multiple users working on excel as well as R projects.

Some screenshots-in a short presentation I made on my notes during K Chine’s presentation

Also, Revolution Analytics is coming out with a Web Services product for R

RevoDeployR: Web Services for R

Both are very powerful uses of R for cloud computing- and it would be interesting if the original cloud computing champion Google gets into the R Project.
