Although we're likely to significantly re-architect our IDS  
infrastructure soon, we would be happy with a more comprehensive and  
modern snort2bro functional equivalent.  Being stuck with the Snort  
v2.2 ruleset is one of the downsides that would be nice to fix.

If we end up modifying snort2bro or writing our own (unlikely), I'll  
advocate that we contribute it to the Bro project.
