I just tried RemObjects Script for .Net.
It works, although I had to use a static factory (var a=A.createA();) from JavaScript instead of the var a=new A() syntax. (ExposeType function only exposes statics!)
Not much documentation and the source is written with Delphi Prism, which is rather unusual for me and the RedGate Reflector.
So: Easy to use and setup, but not much help for advanced scenarios.
Also having to install something instead of just dropping the assemblies in a directory is a negative for me...
