I usually start by installing the latest version of ubuntu on one computer and then duplicate that directory for every client.
Completely diskless clients booting through PXE or iSCSI from single image or from dedicated images from server are also worth to try. This work fast on gigabit networks with dedicated network cards on server per client. Haven't tried this with VDR yet, planning in future.
100Mbps EPIA EK8000 server here, with 2 diskless/deviceless clients. According to Munin, during a typical week : * peak disk IO : 2k blocks read per second, 2k blocks written per second * peak eth0 traffic : 10Mbps to the server, 15Mbps from the server * 2% CPU due to the VDR server process * 8% peak CPU due to DVB + eth devices during recordings or live-view * 80MB memory for all userland apps (VDR + Samba + DNS + MPD, etc. etc.)
