1.  In what sense is a classical charge a limit of an 
Unruh-DeWitt detector?  How is this compatible with the quantum 
nature of the Unruh effect?

2.  Is there such a thing as a classical point charge?  If not, 
what is the classical limit of the Dirac equation?

3.  Does a uniformly accelerating charge actually radiate?  
(Larmor-Schott vs. Abraham-Lorentz-Dirac)

4.  Does a uniformly accelerating charge radiate as seen by a 
coaccelerating observer?  Does a stationary charge radiate as 
seen by an accelerating observer?  Does a charge at rest on a 
table radiate as seen by a freely falling observer?

5.  The corresponding [to 4.] questions for detectors.  

6.  Gravitational analogs of 2.-5.  Relevance to LIGO and other 
prospective experiments?

7.  Is it meaningful to extend the Rindler vacuum to a state 
defined on all of Minkowski space, including the horizons?  Is 
there necessarily a singular stress tensor on the horizons?

8.  Same questions as in 7., but with a uniformly accelerated 
charge present.

9.  Mirror analogs.  What is the significance of the rival 
"vacua" determined by a uniformly accelerating mirror?

10. Black hole analogs. 

11. Ramifications of the subject of vacua near black holes.
