Are the CEP guys looking at LINQ?

CEP (Complex Event Processing) has become a very hot topic in the capital market as Algorithmic Trading gains popularity. TIBCO and Apama are two of the biggest players in the CEP engine market. There are also a handful of other vendors, including Coral8, Gemfire, StreamBase, etc).

One problem in this domain is the standardization of front end language of choice: different products tend to choose different front end approaches, ranging from SQL-like syntax, OO class library to drag-n-drop visual user interface.

I wonder whether any of them are working towards using LINQ as its .NET front end.
