I'm trying to work out how to build a cross-platform desktop app, given a bunch of fairly arbitrary constraints. So, I'll write a little thread on all the possibilities I'm considering and have eliminated, and I'd be interested in people's thoughts. I'll try to mark the succeeding posts in the thread as invisible, so it doesn't spam everyone's timelines to death; apologies if I miss any.
(This may be ongoing as I consider other new ideas.)
