Another commercial product to consider may be netIntercept from Sandstorm 
(www.sandstorm.com).  They came out and talked to BayLISA (www.baylisa.org) 
about this a short time ago, and while it isn't yet doing the line rates 
talked about here, it was interesting.  It's more about demultiplexing TCP 
and decoding protocols without regard to the port number; sort of an 
expert-system.  (I saw it pluck out and display thumbnails of images from a 
gzipped tar file that was FTPd on a high port, IIRC.)

It's a FreeBSD box already built and already tuned.  If I had the money, 
I'd have bought one on the spot.
