Have been doing this with savings and checking accounts at Ally Bank for over 8 years. Have stuff broken down into emergency fund, slush fund, home buying fund, monthly bills, regular checking, funny money, and some "business" labeled accounts for side projects. You can create an account in about a minute when logged in, though to remove an account you do have to call in, but they have no problem doing it. I have open and closed accounts several times a year when a project dries up or we change how doing finances. It also doesn't hurt that they have good interest rates, no foreign expense costs, and don't charge for things like debit cards, checks, autodraft, bill pay, etc. I do think they are USA only though. Not sure how it works for non US citizens.
