I think the named pipes discussion is appropriate to your problem,  
actually. In this situation, I would probably:

1. Create a log directory per-virtual host.
2. Create "error" and "access" subdirectories of all of those.
3. In each "error" and "access" subdirectory, I would create a fifo.
4. For each virtual host, I would configure apache to write access  
logs to the "access" fifo in the appropriate directory; likewise with  
error logs, except to "error".
5. For each fifo, create a service that reads from it (exec < / 
whatever/access/fifo) and execs svlogd in that directory.

The only problem with this is that apache might block until the  
svlogd service is reading from the fifo. The log services aren't  
really "log services" in the runsv sense, so you'd need to handle  
dependencies manually such that they start before apache does. (Some  
thing like <http://sysinit.sourceforge.net> might work, but I haven't  
touched it in a while, and I need to make some bugfixes.)

For more reasons than this, definitely. I'll be so happy when I can  
move to lighttpd.
