Glitz:

All machines should run xdm.  Suggested desktops:
  Enlightenment
  GNOME
  KDE
  Afterstep
Try to jazz it up.

We need Quake2 servers.  We need DOOM.

Disclosure:

Most of the machines we'll bring aren't souped-up hardware.  Turn
this into a selling point:  Put a placard on the size of the machine
saying this is _only_ a P90 with 32MB RAM, etc.  Make people realise
that this has terrific performance in spite of not being the latest
hardware.
