How about Admin intervention. (Like a system event)
Pay one player to Successfully run Cargo (Specially made Icons like Important POW or New technology like "ship designs" for the 4.84 beta 1) which )from one place to the another or pay the guy who successfully stops him. Put a time limit on the Cargo run. Make the price high enough so Trader can hire Escorts/Fighteres/Etc. etc.
The results couldalso determine which base se4lls that ship....
