I wouldn't want to carry all that water, and even after pre-soaking, beans take a long time (as in hours) to cook unless you have a pressure cooker.
My preference is to cook the beans at home and dehydrate. On the trail they'll reconstitute just fine with boiling water and sitting in a cozy 15-20 minutes. Lots less fuss and bother, lots less weight to carry! You can do this with canned beans or with your very own baked bean recipe.
