What a fun service. I can't remember the last time I used the word "fun" in reference to a plain text editor. :) It's really interesting to watch the POSTs fly by and consider the implications of out-of-order updates, breaks in the open downstream "comet" channel, interleaving potentially conflicting text from different clients. A lot of difficult tradeoffs that they seem to have made good -- or at least plausible -- decisions on.
