Let's see. I have 4 productions servers:  DNS, web, mail, and samba; 
with samba locked up on a private net.  Only DNS is current, the rest 
are work in progress.  I just built my test DNS, which will make the 
rest easier.  So MAYBE 8 boxes, with only 4 up 24/7.  Not something to 
throw a server management system at.  I do have a real job which I have 
to work on this afternoon and tonight.
