100 hits per second is not that much relative to what we do.  We may be 
more of an extreme case, though.

Yes, but Apache already knows what virtual host a log line, so it seems 
redundant to do it again in the external program.

I would agree, for 90+% of users, piped logs are probably fine.  But, 
for the rest of us, it seems like we ought to be able to come up with 
some "standard" way of doing high-performance flexible logging.  If 
nothing else but to have more eyes on the code and techniques.
