wanted to probe everyone's reaction and thoughts to MS project velocity. In a nutshell, its an object caching framework with support for dynamically adding nodes while presenting a unified cache view.

It looks interesting, but nothing that hasn't been done a dozen times before. It would be interesting to see how they will integrate this transparently inside .NET, which I think is what we all are looking for (i.e.: cross appdomain object awareness, so true caches are a reality, and object uniquing is truly possible)

Scott Hanselman had a nice podcast with a couple of the leads on the project - http://www.hanselminutes.com/default.aspx?showID=134
