I could also try to put the question another way: How would one capture a significant (e.g., closer to all than to just SYN) packets of a given flows using OpenFlow (maybe a switch sending all traffic to the controller?)? Would it be efficient? Is it even sane?
You definitely don't want to use packet ins to capture packets, because they are limited to a few hundred per second. You can create flows with multiple output actions to efficiently copy packets; I've heard of several real customers who do this. IBM OFTPC and BigSwitch BigTap both implement this kind of feature.
