"Using balistic gate transistors, I assume 100 Ghz is a possibility. Moving
from 100 Mhz to 100 Ghz would divide observing time on an  intensity
interferometer by one million. For low power light sources such stars, the
benefit is even larger: Oberving shorter tails would enhence energy
efficiency and so allows observation of dimer sources."

Unfortunately, 100 Ghz sampling rates are NOT a possibility. Remember, light
is a particle as well as a wave, and if you're sampling at higher than the
rate photons are arriving, most of your samples will be empty. Naturally,
the dimmer the source, the lower the rate at which photons arrive...
