And why reinvent the wheel? Xen is providing exactly that -- light
weight virtualisation similiar to what IBM provided in hardware.
It has the big advantage of being proven technology and does support
multiple kernel already.
I can only say that Xen looks like a good idea also - it's a VM system 
that doesn't really depend on host (and if you have hardware VM support) 
guest OS, and it even has some virtual system migration (over the 
network) built-in. Supporting Xen would automatically mean DFly can run 
more available guest OS-es, not only DFly.

On the other hand, while NetBSD has got Xen running relatively easy, 
FreeBSD is still struggling with it, with no usable results.

(go for Xen 3.0)
