Well, it's very much dependant on your own network.
>From what I know (from presentations of the folk behind Qnet, and 
talks with people actually using it) is that they have a sort of 
"export" module, which allows you to either output the IP's, or parse 
them such that you get a crafted DHCP entry, or special MAC address 
based "alternate VLAN" statement for on a switch etc.

They have templates for a bunch of things, but whether or not one of 
those templates is applicable or even useful in your own network 
remains te be seen each and every time.

The main strength of Qnet is the detection, and even better, the way 
of allowing people to clean themselves, and then get back on the net. 
Having a helpdesk tell (different) people the same line over and over 
again gets tedious. Putting the effort into making a nice explanatory 
webpage get so much more "return on investment"... ;)
