If it is possible however I never saw it in any MP maps I've played . . .
Jedi Academy comes with both jasp.exe and jamp.exe, one for the single player portion and the other for the multiplayer portion. Altough they share a lot of content (e.g: /base map), a lot of specific code are stored in their respective executables, which cannot be attained by the other executable. This happened a lot in Raven games that utilizes the idTech3 engine and in the example of Elite Force 2 (which was developed by Ritual), only one executable is used by both the singleplayer and multiplayer portions and that is why elements from one portion can be used in the other, such as NPC scripting.
