I'm not one to rain on a parade but you've got a few issues to overcome.

1) you would have some major bouncing around anytime you moved the
scope.  It would take forever to stop wobbling.  
2) every time you tilt the scope the dynamics of the support would need
to change.  Those cute little levitating magnetic toys that spin forever
only work when on a level surface.  If you tilt the base they roll off
of their invisible field and onto the desk.  You wouldn't want that
happening to your secondary.  
3)And there's the issue with supporting an object the weight of a
secondary several inches in the air in a magnetic field.  You would need
quite a power source.  

But hey there might be an application out there waiting for the mag-lev
solution.  I just don't think it's supporting secondaries ;-)

Maybe you could hold it up in column of forced air like the beachball
they use to demonstrate fans and vacuume cleaners in department stores. 
Application of the bournulli(sp?) prin. <tic of course>
