In my environment, I'm only virtualizing Linux, so I can use regular x86 CPUs dating back to 1998 for Xen. The only exception is the deployment of Zimbra I'm going to do. It requires Redhat Enterprise Linux 4 and NPTL, so I can't run it paravirtualized, it must run HVM which requires the special processors. However, who today isn't getting new hardware with HVM support?
I just recently embarked to get Zimbra 4.5.* installed on a CentOS 4.5 virtual server. It is indeed possible. Below are my (crude) notes.
disable exim which is pulled in by fetchmail automatically
chkconfig --level 2345 exim off
run the zcs installer and answer Y for most everything
after installing zimbra, comment out the "Defaults requiretty" in/etc/sudoers
to get the queue listings to show up in the admin web page (and stop the error)
If $/GB is a dominant factor, I would suggest Coraid's products. They have a pretty niffy technology which is dead simple and extensively leverages OSS. From my personal experience as a customer, I think they are a bunch of good folks as well. They also seem to constantly be wringing more and more performance our of their systems. Anyway, something to explore if I were you.
I've just completed my thesis and have been quite happy with JabRef which a Java based frontend to Bibtex. It's really quite flexible and works well with LyX, Kile, or WinEdt. While I didn't need the capability, it can also import a whole bunch of formats.
I've had fairly good experiences with the Unison product. It works similarly to rsync but with a few enhanced features. And I quote...
Unison runs on both Windows (95, 98, NT, and 2k) and Unix (Solaris, Linux, etc.) systems. Moreover, Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example.
Unlike a distributed filesystem, Unison is a user-level program: there is no need to hack (or own!) the kernel, or to have superuser privileges on either host.
Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed.
Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an rsh or an encrypted ssh connection. It is careful with network bandwidth, and runs well over slow links such as PPP connections. Transfers of small updates to large files are optimized using a compression protocol similar to rsync.
Unison has a clear and precise specification.
Unison is resilient to failure. It is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures.
Unison is free; full source code is available under the GNU Public License.
Anyway, you might give it a look...

I'm an admin at a similar institution and we're trying to solve the very same problem. I've always been very disappointed as to what FoolProof could do for us. It always seemed to get in the way when we didn't want it to, and it never seemd to really do what we did want it to do.
We're currently looking very seriously into the netboot options. We don't have an Apple server, so we're looking to role our own Linux solution, but I'm not sure the setup time for the server is really going to justify what we would gain. (We don't have *that* many macs -- 1 lab primarily.)
One of the most promising alternative solutions is Mac Admistrator which promises the world for us (linux and/or NT authentication, drive image resortation/sanity chekcing, etc.) I would think it would be something you'd really like to look into.

Robert O'Callahan (a core Mozilla developer) had some fairly insightful comments on Fortress a couple of days ago I personally found interesting...
