sure but bayesian filters require training. so
- their accuracy is poor at start.
- for users who don't retrain the filter, accuracy may never be 
satisfactory. (using a "global" wordlist may help, but not if these 
users receive mail that is different from the one used to train the 
global db).

Chris Idea is to "shoulder" (or boost?) bogo using SA. I would love to 
see the results of this. (I find this better than using public corpuses).

for example, when you install bogo for the first time, you use SA too. 
if SA score is "sure" (<0 or >10 for instance), then train bogofilter 
with this email. There is still a risk of error (FN or FP) of course, 
but for users who don't retrain bogofilter, this is better than nothing.

once the user's wordlist is "mature", SA can be skipped for that user.

one can reduce this by using a conservative setup (disable or lower the 
score of rules that generate FPs).
