ZENworks is the name for at least 3 different Novell products. The Above is now called ZEN for Desktops, and is joined by ZEN for Servers and ZEN for Networks. ZfS is a product that does what ZfD does, but for servers, and ZfN is the same, but for your Cisco, Nortel, Lucent or whatever networking gear.

Eric Schmidt, when he took over Novell, said he wanted 10 ZENs within a year. They didn't quite make it, but they have lots of other killer apps for NDS.
