I guess the salt bath is the best way to completely discharge a lipo. A std nimh light bulb discharger is definately not safe.

As far as shipping goes, a properly padded package should be fine. Tape the holes with something non conductive and the same with the tabs. Unless the lipo shorts it will be fine. Remember that we ship non dmamged lipos all of the time, and the same sharp object could stick thru the package and cause one of them to catch fire. Caution is fine, but blind paranoia does not do anyone any favors.
