Amara this is an interesting comment.  The size of particles that make for
really good meteors are the pea-gravel-ish size and larger, ja?  Gravity
would be the only force which would do much to those orbits on the time
scale of a few hundred years, unless I misunderstood your PhD thesis
(entirely possible.)
