I've had remote start in a manual before. I did have to have to keep it in neutral and the parking brake engaged for it to work but I didn't have those extra steps you described. Its annoying they never offered it In the manual trans. Its not hard to wire it up to the parking brake sensor and have a neutral safety switch to ensure its not in gear. It would be nice if it can all be done with one fob. If there is no way to program a factory remote start fob to an aftermarket unit, is there a way to program the keyless entry/start to an aftermarket fob that supports remote start? I don't like massive keychains and 1 fob is definitely better then 2!
