Are you sure you want to completely disable this system? I understand from your other post (
http://lucasforums.com/showthread.php?s=&threadid=143076) that what reallly bugs you with that system is the automatic healing. (the rapid transit system can be a practical solution qhen bugs are encountered - stucked npcs, triggering xor's second encounter, problems with the sand people disguise) 
 Diabling the automatic healing is pretty easy. In k_sup_gohawk.nss, just remove the following lines:  
 void HealParty()
 {
 object oParty;
 int nCnt = 0;
 for(nCnt; nCnt < 3; nCnt++)
 {
 oParty = GetPartyMemberByIndex(nCnt);
 if(GetIsObjectValid(oParty))
 {
 ApplyEffectToObject(DURATION_TYPE_INSTANT, EffectHeal(500), oParty);
 ApplyEffectToObject(DURATION_TYPE_INSTANT, EffectHealForcePoints(500), oParty);
 }
 }
 } 
 save and compile with k_inc_debug.nss and k_inc_utility.nss
