One of my favourite, easy-to-make, hot sauces is already published here. Check out the page http://www.chillies-down-under.com/habanero-hot-sauce.html
Feel free to try it. Needs no cooking, no special attention except a 24 hour refrigeration time.
I like your idea, but I wonder about postage as well as you do. And some countries has laws about importing food, too. Perhaps it would be easier to exchange recipes, so people can make their own sauces from different countries?
