Just to add to Yoav's remarks.
First we are commited to share DIMES data with the research community and the public in general.
As Yoav said, we are working on a web interface that will allow other people to directly access our databases. It is used at the moment by a group in Hungary, successfuly. It is not fully open now because we need to solve load sharing problems and prioritization of the access.
In the meanwhile, we have supplied data to a few groups worldwide: in the US, Italy, Hungary, Egypt, and Israel. We do have a few additional requests for data from the US and Switzerland which require us to do some more work in data cleaning before they can be answered.
There are already a few scientific papers and technical report, some of them by our group, that were published with DIMES data. We intend to post them in the DIMES website, soon. One example is a short paper in the ACM Comp. Comm. Rev.: http://www.eng.tau.ac.il/~shavitt/pub/CCR05.pdf
