Okay, since you are so nice, let me answer this one :-)

http://freebsd.rambler.ru/ is a nice web search for our
mailing lists. In fact, we're planning on integrating it
into FreeBSD.org

So the state of things with windows dynamic disks in
FreeBSD doesn't seem to have changed much since

I think most of the software in ports is GPL'ed. We'll be
happy to see you offer a new port or support an existing
one. As for the FreeBSD kernel, we can't use GPL'ed code
in the default (generic) one, but we can use it as an
optional feature, or as a loadable (kld) module.

Take a look at this port:

Thanks for your interest!
