IPS technology question.

[snort user <snort.user () gmail com>]

Greetings.

What percentage of the IPS systems are out there, which does not use
co-processors/FPGA etc..

 What percentage of the IPS systems depend on firewalls like iptables
and ip filter ?

I am just trying to get an idea of what is the state of art in the IPS
technology space.

Any information is appreciated.

Thanks
