I'm running a network of 10 clients connected into a Red Hat Linux server. The clients are very old PCs (486 or Pentium I boxes) running Windows 95, with Vista eXceed as their local X-server. They connect to the Linux server via XDM. The ancient clients are starting to fail, and we're also severely short of desk space, so I'd like to use some thin client hardware boxes with their small 'footprint'. LTSP is not so easy for me, as I don't have any administrative rights over our campus DHCP server, and LTSP seems to assume that you do.
What's the best solution? X-terminals are surprisingly expensive (> $400 mostly), and I'd like to keep the costs to a minimum. VNC might be rather too slow?
