Paul, you might want to talk to James Noble, I'm not sure about the NDAs
required by them to run Virtuozzo or Ensim, but I *know* they've got both
and they're looking to migrate to linux-vserver (ensim from what I hear is a
cpu-hog.. and I know firsthand that virtuozzo is about a year behind in
kernel stuff and afaik, they're adding redhat 8 support just this year.)
