see, I think that\'s going too far... hiding gender is easy, race only slightly harder (unless you\'re kran, dwarf or something similarly odd shaped)- it\'s when everyone becomes completely the same size and shape that you get excessive wierdness.
and I don\'t think these should be rare, magical, or all that incredable... how hard is it to get a piece of fabric, pull it up over your face and hide your identity (I own a cloak, and my girlfriend made her own- so the answer to these is- not very.)
