I personally would be interested in contributing to efforts for this kind of support on OpenBSD, but most specifically a port of qemu/kvm.
Virtualbox and Wine are toys in comparison to the kind of tools I would expect to be used on OpenBSD.
If you like the bare-ness and configurability of OpenBSD but want a lot of common desktop applications for a home computer [like Virtualbox and Wine] I highly suggest Gentoo or Arch Linux.
