Can you step up your cost basis indefinitely via the 0% capital gains rate?
As JoeTaxpayer illustrated, yes you can.  However, one thing to remember is that unless you live in a state with no state income tax, there may be state tax to pay on those gains.  Even so, it's likely a good idea if you expect either your income (or the federal capital gains tax rate) to rise in the future.
