failing that exact Phorm gifted model/model...,has anyone got links to the spec tech PDF's of the most common off the shelf Deep Packet Inspection kit in use today, that can help support the general eduction of what they CAN be made to do.

An interesting article on arstechnica from June 2007 about DPI kit and what can be done with it, contains this quote.
"The rise of "lawful intercept" (CALEA) requirements and the growth of online video (both P2P and over HTTP) are making monitoring and shaping increasingly important to ISPs. Because of the firestorm surrounding network neutrality in the US, ISPs here tend to take a cautious approach to using this equipment, but it's far more common overseas.
BT, for instance, recent became Ellacoya's single largest customer, using its gear to support more than 3 million broadband subscribers. According to BT, deep packet inspection enables them to better monitor their network, but it also allows them to apply QoS to two important services. VoIP, to be useful, needs to move quickly, so BT gives it priority on the network. BT also runs its own IPTV system, with the data apparently flowing over the same network as user data. To prevent distortion in the TV signal whenever half the country decides to download an episode of Little Britain using P2P, BT uses QoS to make sure a fixed amount of bandwidth is always available to IPTV."
