Hi Ken,
I would also be very interested to hear about how this is done.
As far as I understand, only by using materials with a negative index
of refraction
(which practically do not exist yet, apart from small micro-samples
using
rather large amounts of energy and other trickery to re-direct the
flow of
photons) could ever reduce the limits of diffraction.
Also, almost a bit off-topic, but I recall an informative thread I
participated in
on the Open Photography forums a while back regarding diffraction and
resolution:
