I just finished reading an interesting article pertaining to the shipment of live coral. The link http://reefkeeping.com/issues/2005-11/eb/index.php talks about wet vs. damp shipping and the result of what appears to be for the most part controlled expierements on the subject. In a nutshell it appears that although maybe not for all coral, but some, that an increased survival rate from shipping could be expected from a "damp" shipment vs a "wet" one, similar to the method used for live rock.
