O.P. RE: Plus Sound Feature Anomaly
Well... This is easily explained if we really knew the way the custom feature works. Because I don't think (and do not expect) the sound is sent each and every time I send the sound.
There should be two instances:
a) the recipient doesn't have the sound, so the client should ask the server to download the sound
b) if the recipient already has the sound, the client wouldn't need to download the sound once again.
Now, this is the way I believe it should work. Perhaps it's the way it works!
Perhaps the client doesn't need to communicate to the server if it already has the sound, once it receives the request to play the sound, then that's enough.
Now, if the signal for the sound to be played is not client-server-client and just client-client, is the IP revealed or something? (this is an offtopic question, sorry, just curiosity)
