The definition of "retail encryption" is somewhat ambiguous.
Different signatories of the Wassenaar agreement implement it slightly
differently.  To my knowledge, the U.S. interpretation is the most
liberal one.  On the other hand, I would be surprised if anybody
claimed that cross-border network traffic was somehow affected by
export regulation just because it was transport-encrypted (and this
seems to be the OP's scenario).
