in theory, you could install the linux compatibility packages (see
compat_linux(8)) and run e.g. VMware Server as a platform for a
Windows VM. I haven't tried this myself yet (although it is on my list
of things to do the next time I'm bored).

a guest OS is always vulnerable to flaws in the host (because the host
controls it), to varying degrees.

nothing's impossible. :) Even if your host OS (OpenBSD) is highly
secure, if your guest is less so and you expose it to the network, it
could be attacked over the same channels it uses to communicate with
the network. The only truly secure machine is one that is not
connected to any network and has no physical access.

clearly, you'd have to evaluate the security of any services or
applications you're running on the network independently of the OS
they're running on top of.
