Note, however, that the IDS component of this, the IDSM-2 (I'm assuming this
is what you are referring to) doesn't exactly have multi-gigabit inspection
capability.  From
http://www.cisco.com/en/US/products/hw/modules/ps2706/products_data_sheet091
86a00801e55dd.html:
"600 megabits per second (Mbps) of IDS inspection provides high-speed
packet-examination capabilities and allows for more protection of a wider
variety of networks and traffic"

It sounds to me like you'd actually get better performance by taking a
gigabit IDS and plugging it into a SPAN port.

That, and it's also a $20K box.

Which is, of course, one of the reasons that I prefer snort.  :)
