I have indeed been giving that a lot of consideration, Kris.  I really
like VirtualBox, been using it a long time and it's done everything
I've ever needed it to and even occasionally surprised me.  I also
really like the ZFS file system.  I probably could build out the
hardware, run OpenSolaris on the bare metal, set up the disk array
NAS/SAN and all that, install the Solaris port of VirtualBox and build
the VMs on top of that (Development, Fedora-based MythTV
cookie-cutter, headless VMs for the kids to connect remotely, etc).

Lots of interesting possibilities.
