Jerry,

Thank you for the rundown.

You wrote "Simple answer - yes.  Although, one of the early signs of CCD
seems to be that affected colonies will not take feed - syrup or pollen
  substitute."

Reading the above comment then focusing on CCD affected colonies only 
and not others in the area:

Does this indicate that CCD affected bees are ignoring feed or not
capable of taking it?
Have the CCD affected bees been observed during the period of refusing /
ignoring presented feed ?

Are the CCD affected bees, if refusing feed material that has been
supplied, continuing with normal foraging activities on flora in the
vicinity of the yard ?

If they are flying to and gathering nectar sources, what is their
behaviour profile during this activity ?

If not flying, what are they doing otherwise ?

Peter
