Thanks, I'll take a look. From your description and my previous thoughts about the problem, the problem I see is that is "whether data should be reliable" and "how many transmissions" are not the sorts of parameters you want. Nobody cares about the number of retransmissions; people care about how much time is spent transmitting. And no connection is ever 100% reliable, so you want more than a Boolean.
