A couple years ago, one of my professors told the class
that he was working on a project with Boeing and some
government agencies (probably the FAA) on a project to
reduce the 757's high wake turbulence.  They were proposing
some type of bolt-on attachment to the wing to cancel
out part of the vortex and prevent the CAA from 
classifying the aircraft as heavy.  

As I understand it, a heavy aircraft pays more to land
at an airport because it requires more separation and
reduces runway capacity at peak times.

Just my $0.02...
