A stimulus question

Barack Obama has repeatedly promised to hold accountable the local officials in charge of spending stimulus dollars. And I see that Joe Biden has now promised "to embarrass them into doing what they are supposed to do." And sure, shame seems like a reasonably strong motivation. But is that all the administration has? (And how does it work? Are the offenders names and faces posted on recovery.gov?) Or is there some other mechanism by which the administration can hold local spenders accountable?
