The "normal" Bro deployment is as a cluster at this point anyway where the manager is dedicated to notice handling and logging (as you've noticed, standalone instances basically suck for anything over 80Mbps). Also, Gilbert has been spending the summer threading the logging framework and I *think* his branch is probably close to being integrated. We basically planned on threading the logging framework from the start for all of the reasons that you mentioned. :)
I started inserting Bro logs into PostgreSQL a long time ago at OSU too with my bro-dblogger project...
If you read the README for that project closely, you can see way back then that I was already heading down the path that we ended up going down with the new logging framework. ;)

The rest of the filter actually works already except for the $writer. :)

We've been poking around at various people and places trying to figure out what a Bro interface would look like and do. I suspect we aren't too far off from movement in this area, but we have no plans yet.

I'm hoping to have a couple of people talk about this specifically at the Bro workshop.
