First of all please remember that mod_status is not the only user of the 
scoreboard, Apache::VMonitor does have a space for vhost :) Of course I 
do realize that users need to enable mod_status and extended status in 
order to get to the extra data. But that's fine.

So there are two different issues here:

1. patching the scoreboard to collect and store this extra info

2. patching mod_status to use this extra info

We can resolve the first issue first and then see how to present this 
info (the second issue).

since mod_status in the extended mode is already doing a lot of work,
how much of an extra overhead will the port/ip info will add?
