It is possible to jump / turn / kite with a group of hunters but it is ridiculously hard to do unless your "lucky". You need to rotate your hunters with each jump and have a main hunter with the largest agro, as long as he is being targeted by the mob and always in front by enough distance then u can jump turn / follow to return your following hunters, its tricky to do though.

I would also say that the best type of kiting I have found with multiboxed hunters allows you to do some great things, you can kite where no hunter has kited before (within smaller areas etc). You simply need to rotate your kiter and drop back your followers. Start kiting a mob as per normal with your other hunters on follow, when you get near to the end of area your kiting in break the follow on your other hunters, set them to follow another hunter, keep running on the main a bit more then fdeath.

The mob then turns and chases the other pack (u leave ur solo hunter where he is), kite to the other end and do the same. Now when you run back this time you pick up the hunter you left on its own on the first run, this means if your using 3 hunters you can happily rotate kite in any spot which has 15 seconds of run space. 4 hunters is preferable in case you get a resist or time delay .
