The core applications from NETWARE have been ported to linux. OES (Open Enterprise Services) composes the central part of what was NETWARE. Things like eDirectory (Around long before Microsofts active Directory), eDirectory integrated DNS and DHCP Services, iPrint, iFolder (around long before the Apple 'i'), NetStorage and more all have been ported from NETWARE into a proprietary package for Linux, now called OES. OES is made specifically to run on SLES (SuSE Linux Enterprise Server) which is a hardened version of Linux.
For a comparison of Netware to OES, you can look here
For small Businesses (100 Users or less) Novell has wrapped many of their products into OWS (Open Workgroup Suite) Small Business Edition. This comes with things like Groupwise, eDirectory, Zenworks. Licencses for SLES and OES as well as licenses for SLED (SuSE Linux Enterprise Desktop) which is a streamlined version of Open SuSE.
No I don't work for Novell, but I do use Novell products a lot. I prefer Novell over Microsoft any day.
