I totally agree.  Since I rely heavily on ACID for my interface into our
sensor, a standard naming convention for the rules makes analyzing the gobs
of alerts much easier.

Another thing to consider is rules that detect different variants of one
common attack -- x86 NOOP comes to mind.  If more than one rule has the same
name (actually, the same 'msg' field), this makes sorting searching a bit
more complicated.   At the same time, do I really care that a particular
NOOP sled is one type vs the other?  It depends. 

The closest thing we have to categorizing rules right now is the
'classification' field.  While it doesn't indicate what file it came from,
it does help do basic grouping of similar rule types.

Changing all of your own rules could be done in a handful of lines with
your scripting language of choice, but I agree -- it might be worthwhile to
make this change in the rules that a distributed w/ Snort.

for what its worth,
