Thanks for that. It's coming back. I now remember I've seen that article but I wasn't thinking of it when I wrote but another one on the same or similar matter. Seems I've concatenated both together in my mind even though they were written decades apart. That said, the original articles seemed conceptually important to me at the time so at least some of the info stuck. It'll be interesting to see if the technology eventually makes into mainstream. I'd put money on it that it will.
