> it shouldn't be hard to avoid typing in the same place [...] if it happens, the person editing will notice within two seconds and just wait a second for the other to finish But if it does happen, it needs to result in a consistent state in both people's editors, right? > In a more realistic example, it would be changing "its" to "it's" concurrently with changing the word to "that". There is no good solution (the server wouldn't know which person to ignore: the apostrophe inserter or the replacer) Discarding the apostrophe seems like a good solution to me, what's wrong with it? As long as, if the replacer hits Undo, "it's" is what is restored. (Not sure if any existing algorithms do so, but I believe it's possible and am intending for the collaborative editor I'm designing to do so. Haven't implemented it yet though, so who knows.)
