What is the point of nude Yoga?

…just stumbled upon a mentioning of nude Yoga. Could somebody explain to me what is that and why?

• Yoga for me is a personal work first of all. If I’m practicing alone – I don’t really care. And from the practical point of view – if I sweat – I would prefer sweat going into clothes which are easier to wash than a Yoga mat.
• If practiced in groups – IMHO – it would only cause distraction. It’s hard enough to take mind from the comparisons like “that man can stretch deeper”, etc. without adding additional fact of “that something on that girl looks prettier than mine”…
• I’m not even sure what I’ll do (as a Yoga teacher) if I would have to teach mixed (men + women) nude Yoga group?! Don’t tell me that average [Western] Yogi practitioner is so detached! It’s laughable!
• And about selling such stuff on DVD for “home practice”: being a realist – I would say that most of the sales are made to very different people with very different purposes (than Yoga practice). I don’t mind that and not judging…

…I’m just asking: Am I’m missing something?
