Of course, a judge's interpretation is the only one that matters, but
my reading of the claims is that several of them could apply to SSM.
(It may apply to only 4-hop networks, and there's a typo in claim 3
which may invalidate claims 3 and 4 meaning that it would only apply
to 2-hop networks, but those are way too subtle calls for a non-lawyer
to make).

(Claims 5-17 don't seem to me to apply to SSM, since they all involve
the sender explicitly requesting something from the network)
