actually forgot to mention the main reason I wanted to comment on this
--Hedman's article adds some bizarre scheme for using VASMIR to change
the inclination of the station. Of course, using a continuous thrust
vehicle to change a highly inclined LEO orbit, as anyone with a basic
understanding of orbital mechanics can tell you, is nuts.
Inclination changes are almost always done at the node (equator), since
you have to be physically AT the latitude of the inclination you want
to reach. Using a continuous thruster for that is impossible. (you
would get, what, 10 minutes of useful thrust per orbit?)

It would be possible to use a VASMIR to raise the station's
orbit--maybe take all the people off, raise it to a highly elliptical
orbit, then do the inclination change at apogee where it's cheaper--but
still using a chemical rocket. But that sounds pretty expensive to me
given the station's mass.
