Lots of interesting comments by Sarah Payne and Chris Bray, most of which make sense to me. But there's one part that I have trouble believing.

In my opinion, a phone version would broaden appeal / access but the most critical issue is the neural nets. XG feels like a very different animal as an opponent - noticeably more opportunistic & aggressive, so some degree of congruence asap seems critical for gnubg to hold ground.

This sounds like psychological confirmation bias to me. I don't think that XG and GNU play differently enough for any human to notice, unless we're talking about the "crippled" modes where the bot intentionally makes errors.

To be more specific, I would guess that over the course of 100 games, there would be only a handful of decisions that GNU 2-ply and XG 3-ply would make differently (excluding those non-contact positions where it doesn't really matter what you play), and I very much doubt that XG would be consistently "more opportunistic and aggressive." I would be happy to be proved wrong, though.
