Joseph Strout and I have gone around the email loop a few times on
the applicability of electron holograph, but have not reached any
conclusion. I think the problem has to be split between physical limits
and signal processing limits. 

I want to know if there is a physical limit that prevents extraction
of adequate information. That is, each electron impact will cause
some damage, but how much damage would be caused by sending an electron
through each .1 micron voxel? There is no mass heating problem,
since these electron impacts can be separated by as much time as desired.
Anybody see an easy way to answer this?
