A +meetme (with some caveats) is likely. The OOC room suggestion is prooobably a hard no. All I can speak to is my own experience, but of all the (four?) wod mushes I dipped my toe into, there was just 0 organic, random RP to be had. Also the OOC rooms were horrible and headache-inducing.
But, every character in Arx is assigned a home room, a private space in which they can idle and chat and watch paint dry as they like.
