The motive to write this program was two fold. I wanted near real-time updates
and I wanted to know who talked last. Hence, AJAX updates occur once every 
second and the user list is sorted by most recently talked with the last user to
talk at the top of the list.

This is written is php 5 but it will probably work in php 4. I wrote it in php 
because that's what I know. Most servers large enough to support more than a 
few conference users can run php without issue. You won't need any PEAR modules 
but you will need command line php. 

Installation is simple. Copy these files into some directory on your conference
web server. Edit usermgmt.conf changing $confCall to your conference and change
$tbdcmd to wherever tlbcmd lives on your system. $updateInterval is how often the 
AJAX updates occur in milliseconds. The use of index.html is optional but if 
you want a nice clean URL like http://myconf.com/usermgmt/ just edit the
refresh tag. 

WARNING: Watch the size of your logfile. The Ajax backend calls tlbcmd once a 
second which will make a big logfile quickly. Skip hacked tlbcmd to log less on
the system where we tested but I don't know if that's in the current release.
