Graham,
1) regarding the IPstack and services white paper from MS, for what ever
it's worth (concidering what Robert has said), you can find the NT versions
(3.51->5) on http://vipe.technion.ac.il/~noamg , including all relevant
Reg.Keys etc.

2) You may also want to check with :
 2.1) Flash Networks (prod=SatBooster) on http://www.flash-networks.com/,
application level spoofing (proxy)
 2.2) Fourelle (prod.=Venturi) , uses similar principal, on
http://www.fourelle.com/

Sincerely,
 Noam Gonnen
