It would be great if there were a similar solution for directly running legacy NeXTSTEP/OPENSTEP binaries on Linux without the system vitualization overhead of something like previous or virtualbox.

Mainly thinking about being able to reuse the NeXTSTEP versions of programs such as FrameMaker, WordPerfect, Quantrix, CedarWord, Adobe Illustrator, Altsys Virtuoso, and so many more.
