I think the arch-users@lists.fifthvision.net list would be happy to host
continuing discussion in this vein. Considering Larry's repeated
attempts to get people to look at arch as a "better fit," it seems
particularly appropriate.

Of course, you'd have to tolerate "arch community" views on a lot of
these issues, but I suspect that might help focus the discussion.
