I think it would be nice if we can just name jail's IPC objects from host environment using syntax like e.g. /JID/name_in_jail or /jail_IP/name_in_jail However, I can't find info whether "/" is legal as the 1st character of IPC object ID. If yes, we should use another prefix. This approach won't work if there are no restriction on IPC object IDs 1st character. Are there any?
