I have a customer that has a program that is called "dataflex", they purchased NOWSSBE thinking that their product would run as well as it did on netware, well much to their surprise, their product "dataflex" with creates a proprietary database every so often needs to be reindexed to work properly. NOWSSBE install the ext3 file system by default and it looks like this program does not like it.. My question to the NOWSSBE product manager at brainshare 2008 was exactly about these types of issues.. I have many customers on NSBS and are running just fine, but if they want people to migrate, you must make sure that their productos and programs run on linux...
