What sort of filters are you after? I wouldn't oppose allowing some basic
commandline switches to filter by source/destination address or port.

Yes, there have been other requesting that too. I haven't been able to
figure out a syntax for flowd.conf that works well for additive/cumulative
tagging. The problem is that the filters are now "one match wins", but
cumulative tagging breaks that a little. Suggestions welcome!
