Got the formal confirmation from travelindochina on my trip to Vietnam. Will try to learn some phrases in vietnamese, but a quick search shows that it is one of the harder world languages to learn to read or write. Easier to learn than Chinese, Arabic or Japanese, but...not easy. It has a lot of subtle tones, as in Chinese, so you can think you are saying a word correctly, but you can be way off.
Well, will will certainly learn the vietnamese noun " ruou bia " from this very important list
