C# + IE9 JS Engine Chakra?

Question

I'm working on a cool C# app, which uses JS a lot for our model layer. We would like to use the IE9 Chakra Javascript engine for speed improvements.

Questions:

• Can I use Chakra in C#, and interact with JS objects as COM objects? (to call functions on JS objects)
• Can I install Chakra separately from IE9? (some users do not have IE9 installed, so it would be easier if they did not have to install IE9, but just Chakra).

Thanks a lot in advance for you expertise.
