Is it possible/recommended to knead dough with disposable latex gloves on?  I'm asking because I have quite long nails and don't find it a very hygienic idea to knead dough with long nails. Not to mention the amount of dough I'd have to pick out from under my nails later on...  Will it transfer any smell/taste to the dough? Would washing your hands with the gloves on change this? 
Why are your fingernails involved in kneading? I've made bread regularly since I was 16, time off for college when I had no kitchen at my disposal, but that's still 30 years of making bread. You should be kneading with the open ball of your hand, and your nails should not be involved at all. My nails are always out-turned, with the bread dough beneath my palms. I can't imagine wearing gloves for kneading; the whole experience of knowing when the bread is sufficiently kneaded has to do with the feel of the dough, and your hand will not be sensitive to that with gloves on.
