Some interesting links from my coworkers about Project Jasper:
Shyam Pather, who is currently attending Mix07 and will be giving the Jasper Mix07 session tomorrow (5/2/07) has a write up on the sessions he has attended so far including the key note. He also discusses the relationship between Project Jasper and the Dynamic Data Controls for ASP.NET also being introduced at Mix07.
Carl Perry has written up a small VB sample using the Jasper framework. The interesting aspect of this sample (beyond showing some of the basic Jasper capabilities) is that one could copy this code, paste it into a vb module, point at their Northwind database and run. Iterative, rapid development at its best. Far as I know, Jasper is the first major O/R framework that supports this type of scenario.
