You could pretty much s/SELinux/Linux VServer/ that comment and it would
still be valid :-).

The classification engine for a Linux-VServer.net kernel would be a
piece of cake, alright. Is there a dummy/skeleton resource classifier
that I could use as a base?

Oh, dear - how many different meanings of the word "vserver" are there?
To compound matters, one project is pretty much the logical inverse of
the other ;-).

Hmm, you could cluster some systems with 2.6 vserver, then allocate
seperate UNIX contexts inside via Linux-Vserver.net, managing resources
on the cluster with CKRM. Then all it would need is some kind of
checkpointing mechanism, and you could have transparent Tandem-class
redundant systems on a pile of cheap x86 boxes! :-D

Roll-your-own HA blade-like systems based on low-power, cheap as chips
Mini-ITX boards anyone?
