1. A system for controlling transmission of data packets through an information network, the information network having a plurality of user workstations communicatively coupled to a network access point (NAP), said system comprising: a Regional Transaction Processor (RTP); and a data Enabling Device (DED), said DED being disposed at the NAP and communicatively coupled to the RTP, said DED containing content match information and operable to: inspect at least content portions of data packets, each data packet comprising a content portion, a header, and a trailer, transiting the NAP; forward an inspected data packet when information within the content portion of a data packet is not substantially similar to content match information; and when information within the content portion of an inspected data packet is substantially similar to content match information, temporarily store the inspected data packet, initiate issuance of a DED message to a recipient user workstation, and invoke the RTP to process a transaction; wherein: the RTP transmits an RTP message to the DED authorizing forwarding of the data packet only when a result of the transaction indicates that forwarding is appropriate; the system further comprises a plurality of DED's, at least one intermediate DED operable to forward the DED message to a DED closest, within the information network, to the recipient user workstation; the plurality of DED's are operable to communicate with each other to prevent transmitting more than one DED message for the same data packet within the information network; processing a transaction based on a user response to the DED message; and the RTP transmits one of a Release_Content message and a Cease_Content message to the DED, based on the result of the transaction.
