As well there should be.  Microsoft has a long history of buying
software companies that have *nix solutions that compete with
their own products, then killing the *nix versions (RealWorld and
other accounting software comes to mind).

At one time HP had a promising Exchange replacement, which they
dropped.  There are those who think that M$ brought pressure on
HP to drop this, and HP probably sells far more systems running
Windows than they do running *nix systems.
