The link above makes Zen sound kinda similar to coLinux. Would this be

Not really. It is similar to coLinux or UML or VMware in that it gets
you another running instance of Linux but that is where the similarity
ends. I am fairly certain that coLinux and UML etc are going away in
favor of Xen. It is on track to be included in RHEL and SuSe Linux and I
am sure others will follow.

I read that Xen takes precautions to isolate some parts of the hardware
and drivers from the rest so a fault in one

Another cool feature (which I have not yet taken advantage of) is that
with Xen you can migrate domains between boxes with shared disk storage
(via iscsi, AoE, fibrechannel, or whatever) with only tens of
milliseconds of downtime to the domain making for some really cool
clustering possibilities. The Xen guys have migrated a Quake server from
one box to another and the players never noticed.
I assume you meant to say "a *running* Quake server".
I have been running my Xen setup for a week and so far I am very
impressed with it and I think that from now on any machine I own, be it
server or desktop, is going to have Xen installed. RAM is cheap and 99%
of cpu cycles go to waste anyway so this sort of consolidation really
makes a lot of sense.
Sounds like it.
