I think that if you guys could create a tool that will let folks do IL-level debugging, that it will do most of what folks would want in a simulator. The trick to building such a tool would be to show the contents of the CIL stack when what you're really doing is stepping through JIT'ed x86 code ... I suspect that the difficulty in doing just this was what prevented VS.NET from doing the same thing ... ;(

I'm not aware of anyone doing a graphical simulation of interpreting IL yet, but I can't think of any real obstacle to doing one. Of course, this wouldn't really tell you much about the MS CLR, since it does JIT compilation, not IL interpretation. However, if you didn't care about performance, you could definitely interpret IL, as evidenced by the interpreters in Mono and Portable.NET. The JVM simulations at artima.com are neat. JasonW and I had casually discussed doing something similar (a set of software toys inspired by artima.com/Bill Venners' book) as an add-on to the AW CLR Internals book we're working on, but we weren't sure if there was enough interest to warrant the (fairly substantial) effort. This seemed especially true given the presence of the 'real' (almost) source code in the Rotor project.
