Results of running the AI deleting FSUIP on a FSX MP HOST
If a client joins the session, in a Glider, and calls up a tow plane, then that Tow plane is seen by the server and sent out to all the other players, BEFORE FSUIPC deletes it from the server. ( FSUIPC/Simconnect is not fast enough to delete) -- ( whoever thought Simconnect was fast !! )
So all players CURRENTLY in the session are stuck with a STATIONARY Tow Plane, on the runway. (Not ideal)
New Clients joining the session will NOT see the Tow plane, as it was deleted from the HOST before they joined.
----------------------
This is probably as good as it can get-- at least as new clients join the server, they are not loaded up with all the Tow Planes that have ever joined the session since the host started the session.
Those Clients that want to remove the Tow Plane can either BUY FSUIPC, or use Traffic Tools to remove any Ghost Tow Planes on runways.
------------------------
I know of no mechanism in FSX MP, that would allow the HOST to remove an AI play from a Client ( apart from a real MP client's User Plane ). To do so would need the server to make a simconnect connection to the client etc etc etc -- not going to happen.
So it would be up to each client to deal with any Ghost Tow planes that got generated AFTER they joined the session.
----------------------------
A theoretical alternative, would be for the Host to FILTER out packets that it sends to clients about the Tow Plane, or possibly inject a "Tow Plane with ID N, has left the session" type packet.
However, without any MP SDK, and that sort of packet info, that is probably not the direction that anyone wants to spend time pursuing.
------------------------------
As someone who runs a 24/7 Multiplayer session, that often runs for many days before resetting, I can see a useful benefit from putting the DELETE AI FSUIPC on my FSX Server.
As a FSX pilot, I would find a FSUIP that could be told to delete AI Tow Planes, when I wanted them deleted, to be convenient, but I would not want FSUIPC to stop me Tow Launching a Glider, IF I wanted to do so. So some way, to turn ON/OFF the delete function, while in the session would be ideal.
Otherwise, if the Tow Planes really bothered me, I would use TrafficTools, or just re-join the session.
