I don't think we need to make our logging more clever than it already
is, when there's plenty of existing software out there to do
post-processing like that. For example, you could direct your logs to
syslog, and let it handle it. I don't think the stock syslogd can do it,
but for example with syslog-ng you could split logs based on regexp on
the message content, like the username.
