A few examples of things I'd like to be able to do:
Every Saturday, automatically transfer X% of last week's revenues to a savings account (which I use to pay my quarterly taxes).
When my personal checking account balance drops below $X, transfer $Y from my savings account at another institution.
On the 10th day of every month, pay off my MasterCard balance from my personal checking account. If doing so would leave less than $X in the account, then don't do it, and alert me (probably by email) every day until I fix it.
Every time my personal account receives a transfer from my business account, transfer X% of that to a retirement account.
Etc....
Of course, the barriers to doing something like this are enormous. Enough that it might simply be impossible, but you're the one who asked for "dream[s]." :)
Good luck!
