Rails - Aug 2005 - Rails shim on top of IIS 6.0 + ISAPI wildcard + HttpModule?

Has anyone out there put some thought into writing a Rails shim on top
of IIS 6.0 + an ISAPI wildcard script mapping + an HttpModule?

In my not-so-spare time I''m spending some time building yet another
.NET to Ruby bridge to learn more about the integration problem
domain.

If someone can point me to the right files in the Rails source
distribution where the low-level HTTP request/response integration
happens it would be greatly appreciated.

Thanks
