No, that's a completely different story. I'm not talking about virtual
servers -- while these should be doable with some Hurd-based solution as
well of course, I don't see any obvious advantages over established
container solutions like Linux-vserver or Virtuozzo here.

Virtual appliances are about running software on your local machine --
only easing management by decoupling the software from the Host system,
using some kind of virtualization solution. Hurdish subenvironments
might allow for a more optimal approach here than the established
full-blown virtualization solutions I believe...
