See what Bush's regime did about it here:

http://change.gov/page/s/yourvision Joining the list of civilised nations, from around the world, in signing the French resolution, will cost him absolutely nothing. This should be a small, but symbolic, part of anyone's vision. He should announce his intent now - before the inauguration, as a shot across Warren's bows, to let him know that he's on the losing side, like Bush, whatever he may smugly think at the moment.
Ask your representatives in Congress to talk to Obama about this too. None of them should hesitate for a minute, if they're reasonable people, from either party.
You can also urge Obama to put the repeal of DOMA and DADT at the top of the agenda, for that matter. But that does involve organising Congress time. All the UN resolution requires is a few minutes' work for the UN ambassador. Nothing else loses any 'priority', for this.
Obama needs a symbolic gesture to offset Warren.
