I would love this, I've wanted it to happen for a long time. I would gladly pay the cost of another account ($12.95) to simultaneously log in with a separate character. I have two characters on one account, both with multiple well geared 99's. I also know for a fact that there are some people that share an account (a mistake they made when they first started the game) but would not speak up because it violates the user agreement. There's been some support for this in the past, too (see my sig).
