How much is the Obama adminstration doing to change Don't Ask, Don't Tell?

I'm following the news stories, but, I realize, I've been resisting blogging about this because I can't figure out what is being changed. This whole we'll get back to you in a year business strikes me as a political feint. And there's:

The Senate, which invited Gates and Mullen to testify Tuesday, is moving cautiously. Worried that they lack the 60 votes needed to break a filibuster, Senate leaders said they might try to add a temporary moratorium on discharges of gay service members to a defense spending bill, whose passage would require only majority approval.

It's Congress that must act to change the policy, so the Obama administration can get out whatever message it thinks sounds best without dealing with any real change. (Ah, change. That word! It's so wonderful as an abstract idea.)
