From Peter Schmuck.
C Lou Palmisano from the Nashville Sounds (Milwaukee Brewers)
SS Robert Valido from the Birmingham Barons (White Sox)
I haven't looked closely at their histories yet, but this seems like good news.
UPDATE (from duck): We've already flipped Lou Palmisano. From The Sun:
"The Orioles selected catcher Lou Palmisano from the Milwaukee Brewers organization with the fifth pick of today's Rule 5 Draft, but then traded him to the Houston Astros for cash considerations."
