Ribbon, planar magnetic, electrostatic omni-driver


I seem to have discovered my favorite flavor speaker design, that is the omni speaker.
Has anyone created this type driver or is one being developed?
Mbl is a great speaker, haven't other designers considered this method of sound dispersion?
I believe a planar magnetic omni driver would be a killer.
Any thoughts on this?

Vandermeulen,
I mean for instance: take a look at the mbl drivers, instead of the leaves expanding and contracting from getting squeezed and relaxed by a motor they would be planar magnetic like the drivers found in the old infinitys. With the center containing sound absorbant material.
Any mbl fans would probably appeciate alternatives that will not break the bank.
IIRC, there was an IEEE article, maybe in the mid 1980's, on "coaxing" omni response from planars using a technique call something like Hoffman Encoding. AFAIK, it never went anywhere commercially. A couple of hours on google might get you the paper, though.
