Tibco goes Silverlight
Tibco likes Silverlight over alternatives, such as Adobe’s Flash platform, because developers can leverage existing skill sets like the ability to develop in C#, McNamara said.
Question: Will this help Silverlight within the investment banks?

I think helping Silverlight outside of the corporate apps space is the bigger challenge. Your average XML and .NET heavy works for a Forbes 500.
Answer: No.
Nothing SilverLight ever will (do anything serious)
didn’t tibco already build something called general interface that was a dot net 2.0 ajax style front end to the TIB?
