And do you want to upload those files to. Since LW is just a client program which doesn't use a central server to store data. Each and every client user (reagrdless of LW, FW, Phex, Bearshrare, etc.) uses the gnutella network to connect each computer with another one (i.e. the computer [user] offering the file to share).
Though your idea seems to be noble, it is not practicable with LW or any other client using the gnutella network.
