XTEX and other MLPs incxluding APL have said they weere interested in selling assets. The problem to date is they are not willing to sell at a price interesting to ANY buyer.
One of the problems for the largest MLPs is finding asets to buy that will not get into trouble with the Feds as restraint of trade. ETP, KMP, and EPD all have assets in OK and TX they would like to buy buy simply could not get Federal approval.
It is an interesting and excellent suggestion however.
