I see that the Astros just signed Bill Hall, which is going to make Jeff Keppinger expendable.  I'd be curious if the Pirates would have any interest in seeing him return to the organization.  Certainly would be a good option to have at any of the infield positions....could challenge (or take over) shortstop from Ronny Cedeno or could be a solid 2nd baseman, if you decided (or injuries forced them) to shuffle the infield.
