I think it's necessary and sufficient for zero-info, large 
populations.

I did suggest a formula, I just never came up with a good 
test to see if it's accurate. It asymptotically approaches 
the mean for large populations so it should be reasonably 
close for populations of say a couple dozen, but it probably 
has some error for really small populations (say, less than 
10). Also, it depended more on the number of "yes" votes 
that are expected to be cast, rather than the number of 
voters. I don't have it handy but if I come across it in my 
saved e-mail I'll post it again.
