Seems Peter Deutsch reached this scheme coincidentally because of a personal promise to Stallman to release Ghostscript as GPL. By using AFPL on the latest two revisions, he was able to commercialize with Printer manufacturers. Those printer manufacturers could legally use the "year-old" GPL versions but preferred to license the latest AFPL version for a fee. This indicates this approach can be effective! BTW, the interview includes several gems, for example when Deutsch gives his prediction on the result of a back then hypothetical event of Netscape releasing their browser as Free Software. Excellent read. matt,

The proprietary version was Aladdin Ghostscript and the free & libre version was GPL Ghostscript. GPL-G lagged behind Aladdin-G by 1 year or about two revisions. Artifex has moved away from that model now. I'm not sure why, but my presumption is that after two decades the business side was well enough established that it could forego the overhead of managing two streams. Here is an interview with L.

I haven't understood what you meant by it. What do you mean 'modifications'? Do the developers guarantee that modifications will be open-sourced? I hope you have time to describe how your idea will work in detail. I think you should write a longer essay about this idea. I haven’t understood what you meant by it.

I'm not sure if all of their additions are released, though. From memory, Crossover Office does a similar thing with Wine: adding proprietary additions to Wine, and then progressively releasing them.
