According to the Steam code discovered by SteamDB founder Pavel Djundik, Valve seems to be developing a P2P LAN transfer tool for Steam, which allows devices on the LAN to transfer games to each other without downloading from the server.
Pavel Djundik said that one of the uses of this tool is to transfer games from a PC to a Steam Deck handheld, which will read the games installed on the disk, eliminating the decryption step for downloading the game.
In addition, this tool seems to be more suitable for university dormitories. If college students are too shy to buy games, they can open a Steam family-sharing account, and then transfer games to each other through the P2P tool LAN.
Some developers have also found that Steam is already testing this feature. Users need to add the “-dev” suffix to the shortcut of the Steam beta client, and then set one device to “@PeerContentClientMode” and the other device to “@PeerContentServerMode” in the control, and then the transfer can be performed, but this function is currently available. Not yet.
