I thought NextStep was from Next; being that OpenStep is open-source, can you really buy it from somebody?
Update:
OPENSTEP was an OS that both updated NeXTSTEP and provided support for the OpenStep APIs. If you're interested, you may wish to look into GNUStep, which is the GNU clone of OpenStep, I think?? *shrug*
**confused**
