I assume you mean a specific domain, rather then a specific system user, 
right?

see: parse your log.
limiting: some scripts that disables a website after checking the traffic 
report.

For parsing the logs there are 2 options:
1. parse the access.log
or
2. create a very simple logformat, which logs "$domain $bytessend", s.th. like 
this:
LogFormat               "%v %B" traffic
CustomLog               /var/log/apache/traffic.log traffic

See http://httpd.apache.org/docs-2.0/mod/mod_log_config.html.en#formats for 
description about the %v and %B. This gives you a log like this:

phpbb.de 0
phpbb.de 4583
phpbb.de 7444
phpbb.de 75
phpbb.de 693

You only need to read that log with a script, split the lines on <whitespace> 
and sum the numbers up. I would use a simple python script, for example:
#!/usr/bin/python
import sys, string, re

dom = sys.argv[1]
send = 0

while 1:
        line = sys.stdin.readline()
        if line == "":
                break

        (domain, bytes) = re.split(" ", string.strip(line))
        if domain == dom:
                send += int(bytes)

print send

Usage:
./traffic.py phpbb.de < /var/log/apache/traffic.log

Gives you:
14202493

Now you know how many traffic a domain makes, you only need to disable a 
virtualhost if the limit has been reached.

I would suggest to put every virtualhost in a seperate file, then you only 
need to move a configfile away and SIGHUP apache to enforce the limit.
