  • I know that TWiki [] locks the page while you're doing edits. People who try to edit the page while it's locked get a polite message saying that you're editing it. Locks expire after (IIRC) a configurable amount of time to prevent the "last-item-todo-before-vacation" phenomenon...
    • Well, yes, it's the classic "distributed exclusive lock" problem, which people have been working on for years. There are ways of dealing with it; problem is that any good solutions require some cooperation (i.e. running code) on the client side, and that's hard to do with www. Well, it's easy, in principle, since we do have javascript... but I haven't seen anybody try this. Alternatively, the necessary bits of code could be wetware -- but that has its own set of problems. :-)
