OK, I guess I didn't really understand what "filter sharing in Canoga" 
meant. I think *of course* you should allow filters to be shared, but 
maybe Chandler itself shouldn't have features for doing the sharing. 
Put an import/export feature into Chandler and let people take care of 
distributing and finding filters out of band. Then the security problem 
is reduced to the same as any software: don't install it if you don't 
trust it.
