+DOSP has been in use since the early days of FOSS.  Companies (it's always
+companies) tend to use it to preserve commercial advantage while still taking
+advantage of open source dynamics.  We suspect that as the delay increases, the
+benefits of open source decrease. Exploring the tradeoff between those
+benefits and the period of exclusiv exploitation might merit future research.
+
+From this research and in conversation with OTS's clients, we see some evidence
+that DOSP works best for fast-moving, cutting-edge software, where access to the
+latest features is commercially significant.  For software whose year-old
+versions are suitable replacements for the latest proprietary versions, the
+market segmentation offered by DOSP disappears.  Those cases essentially
+collapse down to a dual-licensing scheme with proprietary and A/GPL options.
