Yeah, I was counting on that, actually. But I get your point: it's
measuring two different things. I did not have the other use case in
mind (application layer to application layer) until Lars mentioned it. I
suppose doing both would be worthwhile, and probably some of the
time-keeping logic can be reused.

Still leaves the question of whether it's possible to get to the TCP
timestamps short of sniffing the packets, though... Anyone knows?
