Hi Rodrigo and anybody else who is interested. There is a mailing list
concerning the effort to make an interop solution using the existing
ruby interpreter and the .net CLR together. Go to the following url to
join: http://lists.sourceforge.net/lists/listinfo/rubydotnet-developer.
Check out the archive at
http://sourceforge.net/mailarchive/forum.php?forum_id=34312.

As you will discover if you check out the archives there are a at
least two teams working separately on this and they have both made
working releases!

Cheers,

Thomas
