mod_bandwidth - Server wide per-account set limit

[XPerties]

Does the cPanel install of mod_bandwidth allow you to set a server wide bandwidth limit? I have a server with about 1100 clients on it and I need to set the limit to 10GB per day.

Well, the cPanel install itself only offers the ability to limit on a per account basis from shell. Looking at the mod_bandwidth site quickly, it seems to suggest that it cannot be done server-wide, though I haven't tried:

You could also look at mod_throttle too.

I've found lots of tutorials about mod_throttle such as http://www.webhostgear.com/160.html and all of them say:

Edit your /etc/httpd/conf/httpd.conf and locate the virtualhost entry for the site you wish to throttle. Just BEFORE the </VirtualHost> entry, insert:

<IfModule mod_throttle.c>
ThrottlePolicy Volume 10G 30d
</IfModule>
<Location /throttle-me>
SetHandler throttle-me
</Location>

With 1100 clients on one server, having to edit each one would takes days. Any idea what I can do to set this server wide.
