Have you had any problems with interactions with other auditing going on on the system at the same time (or resulting inefficiency)? Our auditpipe(4) facility allows subscribing to classes of events independently from the global trail, but currently that's not easily accessible from the command line. One idea I've pondered is teaching auditreduce, when run on an audit pipe, to program the filters on the command line into the audit pipe it's accessing via ioctl, which would help eliminate undesired records from being exposed to audit pipe consumers, as well as allowing them to avoid modifying the system audit configuration.

(Details on what sorts of filters can be programmed are documented in auditpipe(4))
