Allowing players to transfer items will enable many new opportunities
Opportunities like what, buying items from Chinese game farmers? I can think of no worse possible "opportunity" to offer the Skyrim gaming community, not any other likely result.
It would make more sense just to allow players to add any item they wish to their inventory without any outside oversight, trading, or restriction. This isn't a MMORPG, so why should they restrict what I can have in my game to what I can find to "trade" with somebody else?
Bonus points because hey, YOU CAN ALREADY DO THAT (via console commands.) Once there's a system in place allowing mods on consoles, adding such a function to consoles would also be easy (essentailly just a matter of making an interface for the existing command).
Wanna trade? You can still do that. Chuck you item you are "trading away" in the trash, then have your "trading buddy" add the same item to inventory via the existing commands.
