You can do aerotow over the net (multiplayer). You need actual cvs-source and data for this. Up to now, only one glider and one motor-aircraft are capable of this, the j3cub and the Bocian.

Taxi the J3 within 60m to the bocian. The bocian pilot has to press Ctrl-o. Both pilots should see in the console window, that they are towed to each other. Then the J3 pilot can taxi. As long as we have no instrument displaying the distance between the two aircrafts, the J3 pilot should watch /sim/hitches/aerotow/tow/dist and /sim/hitches/aerotow/tow/dist-time-lag-corrected in the property browser. Be very slow if the dist gets near 60m, the length of the tow. Increase the speed slowly. Both pilots should try to lift of gently. Both pilots can release the tow by pressing "O" (Shift-o).

If you are not using a local network connection, both pilots should log in on the same server to minimize the time lag. The time lag will still rather large. Therefore /sim/hitches/aerotow/tow/dist and /sim/hitches/aerotow/tow/dist-time-lag-corrected differ significantly (the second value is the estimated dist, the other pilot is seeing right now).

If you fail to tow the two aircrafts, both of you should restart (not reset) flightgear. There is a bug in the path cache of the property tree, which sometimes causes this behavior.
