it would be nice to set up my old server computer to host ZDoom games for people in a pinch. but I don't want to play with them all the time. So i'd like to be able to set it up ad just leave it and not have to worry about my player standing there and getting in people's way and possibly breaking scripts.
and now that ZDoom has that external console thing for crashes, you could just add an editbox to have it send console commands when needed and maybe a "jumpin" command to get yourself spawned and playable (and "jumpout" too maybe

sure it would be kinda funky, but it would work... i'm sure some of the funkyness would be worked out eventually
