British, American and Australian use different words too, and even have different meanings for the same words (eg. fanny, boot, thongs). Yet anybody requesting translation between these would be laughed out of court, and rightly so.
Also, doesn't your claim that BCS speakers are attuned to different dialect groups and understand their terms even further undermine the claim that there's an actual need for translation? By and large, speakers of English aren't (although thanks to Hollywood everybody knows some American), but an Aussie in NYC or a Brit in Melbourne is not going to have any real issues communicating.
