Both are incomplete. The approaches share no code. The conversation Ted cites is from nearly a year ago (and is nought but our platitudes that the authors get together on the problem which didn't happen; the context did not help w/ one part-time on the job and the other a summer intern). Neither has a sponsor. The "Online schema update" is at least used in a few places, cautiously. What should happen is we should pull out both and replace with a working online schema mechanism. Until that happens undo at least one of them before someone other than J-D gets hurt. I vote for pulling "Online schema update". St.Ack
