Well, since it was asked: Lyra2's team is with what the panel believes
to be the best approach, whatever that may be (and also whether or not
our vote counts ;) )

Actually, there is a point in any competition in which it is hard not to
think "if only these guys had worked together from the start, we
probably would have a much better solution combining their ideas". But
since humans seem to bring better ideas to the table when they are
competing instead of when they are at a "task force", competitions do
have their purpose...

Maybe the said task force would be the natural step after the
competition declares its winner(s) (?). We would surely enjoy being part
of that.
