Multi-Account Budgeting Tools/Accounts/Services
I sort of do this with credit cards. I actually have 4 AMEX cards that I've accumulated over the years. Certain types of expenses go on each card ("General expenses", recurring bills, car-related and business-related) I use AMEX because they have pretty rich iPhone/Android applications to access your accounts and a rich set of alerts. So if we exceed our budget for gas, we get an email about it. Do whatever works for you, but you need to avoid the temptation to over-complicate.
