Id gladly sacrifice transaction fees or even merged mining fees in return for one feature I think is missing still. Eclipse has SMS notification for hash rate (and even found blocks), which is really cool. Im not sure how he does it and pays for it, it cant be free to send a dozen SMS messages across the globe for any miner, but its neat. Paypal payout is also something that could appeal particularly to newbies, even if a fat fee is taken. That fee could also form a small source of revenue.
