Alea,
I hear you, but I would not want a CEO to be solely guided by appearance to shareholders.
Because there is a void of any real information, it is impossible to gauge the cost/benefit of the deal.
From a cost perspective, Wave is cash poor so there really is no other means to fund development like this. It is favorable to Wave paying cash (Wave would have sold shares in this scenario as well).
