I talked with StepStone a month ago about some stuff including exactly this. Objective-C as a PD language would help establish it more strongly. > How is the IBM RS6000 doing it? > > They licensed DPS from Adobe, Objective-C from StepStone, and NextStep > from NeXT.

OSF is supposed to adopt Mach so I would anticipate a Mach AIX. I would have expected it to be here already, in fact.

We developed a NeXTstep-like API for OpenWindows 2.0 XView (aka Open Look). 5000 LOC. With that it took hours to port substantial applications from NeXT to Sun. It is faster 'tween NeXT and RS/6000. > What vendors have licensed NeXTSTEP? > > IBM's the only one, I believe. Yep. I would hazard that until NeXTstep is selling 25% of all Unix GUIs that there will be no more buy-ins. What still puzzles me is the lack of people jumping into DPS. Does anyone know the license costs and arrangements? DEC was making a move; any word? Is Adobe limiting the adoption?
