  First, if TCP-INTERECPT code were modified to scale... The next router
  would intercept and "rate limit" the ACKS to only succesfully
  connections, as is true with SYN's, as well. SYN PATH, and ACK PATH
  would be part of the RSVP END-TO-END CDR records... And a SYN would
  not be the billable unit, completed SYN-PATHS would be. ACKS would not
  be either, only completed ACK-PATHS. Flow shifts   
  would generate "Convergence" CDR records..
  to handle that connectionless attitude.. :) 
  Also, RSVP today implies a genuine "commitment rate"... 
  Perhaps *commodity* TCP flows could create 
  0K CIR RSVP's, and just track actual utilization..

  BTW: Fraudulent ACK's would be lacking valid SYN's, as well as
  No one to bill..... 

  And a quick trip to "Disney Land".....

   But, *PHEW*, *would* we be *forced* to
  control BOGON IP's.....:}

   IOPS tightly secured model *everywhere*!
