PayPal Alternative? - What's your opinion?

I'm thinking about opening an electronic checking account with ING that would allow me to avoid PayPal fees. Basically the account would allow me to send money to anyone as long as I had their email address. Once I direct the funds to go to that person, ING pulls the money from my account, and sends the recipient an email that money is available. The recipient clicks the link in the email, inputs their own bank routing number and account number, and - zip - the money is theirs.

Does anyone already use this? Or would you be willing to input your bank info to receive money in this way?
