I can't ever see Dublin being sold as a whole unit, but parts of it quite easily could be. The IMF/EU won't give a crap if there is money to be got from it and as pointed out they are running the show these days. Would bring down the total debt or death as Jamie2k9 calls it.
I have always thought a competing terminal would be no harm to be honest...not sure O'Leary is the man but it would definitely break up the hold the DAA have over everything.
