yeah in the manga kakashi says that she builds up an enormous amount of chakra when she goes to punch and releases it outwards at the exact moment of impact. so it isn't that just any shinobi could do it, only the ones with precise chakra control. which means out of the regular teams only neji and possibly hinata are the only others that could do it but their style of fighting is completely different.
