Also, even if you had the correct programs, the way you would need to do this is PS3 <- Laptop <- Modem/Router(With connections bridged obviously). Not to mention that I seriously doubt that the data for the said file share game mode will be sent separate, and or recognisable compared to other data. And all that, before realising we have no idea how to hack the game mode itself, and get it back onto the game console.
Just letting you also know, people have modded custom game types on xbox using a JTAG, I have one with 50k XP per kill(Impossible to do in game settings) I use for Combat Training.
Dude I said it was just an idea. Chill. And I am well aware of using proxy servers because I used it to download a trailer from the Playstation Store directly to my laptop.
