Well, I've looked into this quite a bit for my own platform that I'm developing
(which, as I've mentioned to you before, I have the desire -- if not yet
exactly the confidence -- of building an implementation of Factor the language
on top of). At least I've looked extensively into the CLR. There are a
number of possibilities, ranging from hosting the CLR through native interfaces
and interacting with the Managed environment through this all the way to
intercepting the JIT compiler calls and injecting code there (again through
native interfaces). ANd there are a number of stops in between.
I will of course be adding this functionality first to my own environment, but
am very happy to share any knowledge and or code that I acquire along the way.
Perhaps, if anyone's interested, we might start such a project from the Factor
end.

As for integration, I can see from your description of Factor's host
integration that we may indeed have different notions about this. Compared to
Lisp or Scheme I'm sure that Factor comes out ahead, no doubt about it. When I
speak about integration, however, I am talking about integration with
mainstream computing runtimes -- like .NET's Common Language Runtime or J2EE --
an integration that would make it possible to use Factor fluidly and easily
alongside such languages as Java and C#
That makes sense, Michael. Interop with mainstream managed platforms would be
great, but the interfaces for doing so are somewhat daunting. JNI is a
nightmare. I've heard rumors that CLR objects can interop through COM
interfaces, which we could potentially use through Factor's COM bridge, but
documentation is scarce—is the ABI used between native and CLR code by C++/CLI
documented anywhere? At any rate, the lack of finalizers or other automatic
resource management on the Factor side would still make managing references to
Java or C# objects inconvenient. It's definitely something worth exploring
deeper, though.
