Thinking about this some more, a licensing agreement would likely have to also include the ability to sub-license the resulting software to markets outside the car player / portable player / home receiver / non-competitive-with-DNNA markets to qualify as a viable business case. I'd hope that RISCOS Ltd get a significant revenue stream from somewhere other than sales of 3900 upgrades that they quote in their end of year 4 press release (they currently charge ~£85 for the ROM).

I'm finding it difficult to think of something that could benefit from a neat embedded player that DNNA isn't already selling or likely to be working hard to license its technology. DAB / HD Radio player? Unless a significant revenue stream could be made by sub-licensing in-car entertainment solutions.
