Novell is an intresting system to say the least, and your miniunm specs to run 6.0 are crazy (256 megs of ram MININUM! any less and it will run slower than windows XP on a 486 )
You need to have a copy of dos to boot from to install it
...Yeah, but think about it. Novell's targets for Netware 6 are people who really need the power Novell puts out. I mean, I've been told that Formula One racers use Novell to monitor their cars! Since anything can be represented as a leaf in an NDS tree, they can use Netware to poll sensors all throughout the car, in real time. That's not a use most people would encounter, but I thought it was pretty cool.
Also, most people don't realize that Netware is a Network Operating System. The question about Netware being able to "go online" is a great example. You can put a Netware 5.x/6.x server on the internet, and I think there's a TCP/IP stack available for some earlier versions (correct me if I'm wrong), but to my knowledge there's not a web browser or any other client application available for Netware. But, once it's on the internet, it can certainly make an excellent web/FTP/database/file/whatever server you'd want it to be. Unlike Microsoft's current server offerings, you can't really use Netware as a daily desktop, ie, mail, web, word processing, etc.
...That's what I'm aware of, at least.
