I'm still not seeing a case where a node could see conflicting
transactions on the network as part of a micropayment channel, and not
know it was observing the resolution of a channel rather than a likely
retail double spend.
If both transactions have been broadcast, then one of the conflicting
members of the set will have nSequence adjustments.
Maybe a clever griefer could try to make their retail double spend look
like a micropayment channel, but it seems like they'd be missing the
other identifiable markers of that protocol.
