Support in case of a sales
As you guys mentioned, if Novell was bought up by another company (in the way Oracle bought Virtual Iron) they'd probably end up keeping their support staff. Where I work, most of our core services run on netware (which for some reason runs like a slug on VMware, and we have a LOT of virtual servers) and we have some new stuff that is MS only and Identity Manager usually does a good job of keeping our eDIrectory synchronised to AD nicely - so as long as bug fixes were kept up and support contracts honoured by competent people, that's probably what most of us would worry about.
