Cloud Computing and BSD’s Place In It

I am a Linux guy.  But I am also a big lover and user of OpenBSD and FreeBSD.  This got me to thinking of BSD and it’s place in Cloud Computing.  In terms of Amazon Web Services EC2 I have yet to see it.  When checking the FreeBSD and OpenBSD projects I have yet to see it at all in a Xen form.  There are a few posting regarding getting it to sort of work.  There is a wiki page for FreeBSD project dedicated to a Xen port.  I believe this lack of Xen support will not help BSDs to compete with Linux flavors.  I would love to be able to use BSD for certain roles.
