We have over 100 Pro Tools stations at the school I work for in my day job. We use simple braided security wire with cable ferrules. Take a length of wire that will provide enough for a nice service loop, string the ilok thru one end, pull the wire thru the hole in the pedestal on iMacs or in the Kensington lock post on Mac Pros (or some other secure point - say a rack rail), then put both ends thru the ferrule and crimp. Haven't had one stolen this way, and - with how cheap they are to make - if we need to remove the ilok for service, a snip of the bolt cutters later we're good to go. And we don't need to go into the machine each time we need to service the loks (which is not very often). If the initial loop is long enough, we can get 3-4 uses from one length of wire. Simple, cheap, secure. One roll of wire may cost $100 or so (the ferrules cost pennies each), but that pales in comparison to the value of the locks. Hope this helps!
