Be aware that mod_cband has quite a horrible bug.  This is a Debian bug
report, but the same problem applies to FreeBSD.  Be sure to read the
entire bug, not just the original report.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=418645

Regarding alternatives: there aren't.  Bandwidth limiting is a
long-standing feature of Apache that's missing, which is a huge
disappointment.

The best solution I've found on FreeBSD is to use pf(4) with ALTQ,
and give each VirtualHost its own IP address, then rate-limit the IP
address using pf(4).  Yes, I realise this is impractical for sites
which have many vhosts and use name-based virtualhosts.

Welcome to my world...
