The behaviour of -from is unintuitive. It just delivers any address / hostname that the computer is connected to. (Well maybe the primary) This doesn't serve in cases of vpn tunnels, where the destination route passes trough the tunnel (routing table), but the connecting client delivers the public / outside address to the server, so the server reconnects to a different address using another route instead of the tunnel. Therefore I propose: leave the -from option to explicitly define an origin. But change the default value of -from to reflect the origin according to the routing table (and the respective device).
Have a look for a nasty example: http://bugs.kde.org/show_bug.cgi?id=139639
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
