DreamMSX has informed me they now have an official site. At least now we know the DreamMSX is definately alive and well. Here is what was stated in the email:

Now there’s an official site for DreamMSX, which will be first updated when a new version comes out. Its URL (not sure if it will be definitive, but it works for now) is http://dreammsx.cjb.net.

Yay! That is good news for us.
