I appreciate this thread and resultant conversations; and also admit that it's firmly in the territory of stuff that I don't know what to think about. It seems clear that the ecosystem around tx confirmation -- most obviously mining, but also other stuff -- is going to be one of those emergent ecosystems that you can't foresee in advance. Or at least, I can't.

And I have no intuition of what's good or bad, except that the whole dust issue is going to be a thing that everyone thinks about all the time and that's one of the central constructs in how the network unfolds. Either that, or it will be a Mountains of Madness-style dead relic.
