if one node is just slow enough in responding that it falls outside the timeout, you could get an annoying situation where that node is out-of-step forever after. i guess it depends how often incoming lines arrive. if it's an interactive session, i guess it might not matter too much - i can see how this might be useful controlling many shell sessions at once. you could make things more reliable by tagging requests and replies, but even then there's the question of what to do when sessions diverge (assuming that's what you're doing). interesting.
