What is the price of the Middle Tier Enterprise Server license? Is it release yet?

Also, the white paper raise some questions regarding the programming from a win application. The Enterprise Server and the SQL Server Database can be in two different network, right?

How do you call the Enterprise Server services from a win application. How the data binding is done?

I hope my questions were clear. We bought your Framework and want to access a foreign database (can it be a Oracle database?)

Your framework is great!

A quick answer will be greatly appreciated.
