It would be really great if you could get a ruby compiler for the .Net
platform but I think that's a very hard goal to reach.  Ruby is a very
dynamic language and a lot of things can't really be done at compile

So you pretty much need a compiler which will dynamically compile part
of the program at run-time.  After that you need to rewrite all of the
ruby core libraries in C# (or another .Net language)

Also the .Net platform is really not optimal for dynamic languages.

A more realistic goal for starter would be to integrate the ruby
interpreter and mono.  Much in the same way as activestate has done with
perl.  That way you could call .Net classes and code from ruby and the
other way around but it would still be two runtimes running at the same

I believe one of the ximian guys has an example on how to do this for

I personally believe that a much more interesting goal would be to get a
ruby compiler running on the perl6 vm known as parrot.  Unfortunately
parrot isn't enough far ahead for that... yet

Lastly.. have you checked this out?
