+ Remote TCP connections were historically sometimes used to share
+ a single session bus between login sessions of the same user on
+ different machines within a trusted local area network, in
+ conjunction with unencrypted remote X11, a NFS-shared home
+ directory and NIS (YP) authentication. This is insecure against
+ an attacker on the same LAN and should be considered strongly
+ deprecated; more specifically, it is insecure in the same ways
+ and for the same reasons as unencrypted remote X11 and NFSv2/NFSv3.
+ The D-Bus maintainers
+ recommend using a separate session bus per (user, machine) pair,
+ only accessible from within that machine.
