Visual Studio style editor for an application-specific scripting language?

Right now I only know about Visual Studio 2008 Shell and the custom control used in the Snippet Compiler.

Also is VS shell suitable for this job? I don't know if it's a custom control or a standalone app? Any tutorials about it?

I would imagine the Snippet Compiler's custom control to be usable and therefore should work, but I still want to know if there are better alternatives out there?

It doesn't have to have everything like step through debuggers which the app itself doesn't support.

Have you looked at the Visual Studio SDK? Also, there are many resources available on Visual Studio Extensibility.
