Note that it depends how you use it. Our idea was not to use it as
a hash key (which would certainly be unwise), but as an extra piece
of information that a blind attacker would have to guess to insert
packets into a connection.  It looked like it might work, however
the big stumbling block was that not all flows were actually sending
with a consistent flow label.
