Sorry I'm coming to this thread a bit late. I'm going to have to take

wanted to say that in the short
time I've been working with snort, the thing that's struck me as a 
pain are the events with sigs that aren't classified at all. Maybe 
this is not the role of the engine itself, 
but I'd almost like to see snort refuse to load rules that match sigs 
that are missing a class.

I love the idea of using tags (many to many) rather than a straight 
sig class (one to many), but in the case of illustrating 
protocols/services in play for 
the sig I'd say the data is already there. It should be up to the log 
viewer or analyst to query for ports, etc.

Also, integers ftw! I'd love it if the ids for these new class/tag 
records could be defined up front, but I guess that's one of those 
things.

Which rules without classtype are you referring to? I don't see any 
rules (regular, shared object and preprocessor) without a classtype at 
all.
