Keep in mind, I believe, that the DAF may have a "name" or "title", but that you (or a Rev Trust) does not "own" the DAF. Once you contribute money to the DAF, the DAF (or, more specifically, the overall fund that owns everyone's DAF) is the owner. When you die, the DAF is not considered a part of your estate. This is because you have already given away the money to the DAF. That is why you get your charitable deduction in the year that you donate the money to the DAF and not when you advise the funds go to a specific charity. Although you do not own the DAF funds, you have the right to Advise to what organization to donate the funds held in the DAF. Hence, Donor Advised Fund.
That being said, you may have the ability to name the DAF, but that only determines the name of the "donor" on the checks going out. Also remember, it would generally not make any difference if you donated (during your lifetime) from an account in your name or from your revocable trust. As has already been mentioned, you can make an additional contribution to the DAF upon your death.
