I personally use this:

[multiplayer]
playable = true
hotseat_turns = true
hotseat_scroll = false
hotseat_update_ai_camera = false
hotseat_disable_papal_elections = false
hotseat_autoresolve_battles = false
hotseat_save_prefs = true
hotseat_disable_console = false
hotseat_validate_diplomacy = true

and it seems to work fine - maybe I didn't had the chance to fully test it ...
