At present, Bind on Account items may only be transferred through our in-game mailing system. Thus, all in-game mailing restrictions (same realm, same faction, etc) apply to the tranference of BoA items. You've my sincere apologies for any confusion, Harthvada! If you're curious, additional information regarding account-bound pieces may be found here:
With that said, if you happen to possess a BoA item in a character's inventory at the time of that character's transfer, the item will move happily between accounts or between realms. Once the character arrives at its destination, it can then share the item with all eligible characters (that are of the same realm and faction, of course). :)
