> Thanks Adrian - will check out the link….would you use "vunify" instead of "vhashify"? I've not tried either yet, but it looks like vhashify can have some problems over time with duplicate links etc? Appreciate the help(!)

I just name the concept, vunify/vhashify is all the same in my view.
There is currently only one VServer installation where I use vhasify to
run 130 webservers on a cluster and save some ram. In all other cases it
is more important to me to have the vservers as independent management
containers on seperate disks (drbd in this case) to be able to do some
manual load balancing.
However, I did a multiseat terminal with USB-VGA-Adapters with my local
LUG for an exhibition, 4 seats worked very well with some P4 and 4GB
RAM. These seats had been used for some web surfing. How much resources
you need depends mostly on
- how many different applications do the peopel run?
- how much ram do they need? Which part of that is just because of
  loading the binaries/libraries?
- how cpu-bound are these applications?

A partner runs 5 web/mail accounts on 1 KVM with 1-2GB RAM, no
VServer there. On the other hand a single firefox can swallow 2GB RAM
and more.
