We use several of the Predator products at our shop; their DNC, MDC (data collection and machine tool monitoring, Tracker (Tool and Guage Crib software).
We really like them all, got them from Manufacturing Information Solutions www.mis-group.com
If you need any specific questions, just ask, I'll do my best, I have used their DNC to do some interesting and non-DNC type things like send e-mails from commands sent from my control and printing out the program when I do a remote request to download my G-code programs. Powerfull stuff to say the least.
