I see this as an educational project and, as such, it's neat and inspiring for kids. A cool looking lash-up of hardware with blinking LED's is always cool. Beyond that a computer running Xen and a bunch of VM's is far more convenient, useful, reliable and probably more powerful. Towards the other end of the scale, for example, we have a rack full of 1RU machines we use to run FEA and other purposes.
