Hi Ben - welcome to the forum
gip1984, theoretically, HIIT can be applied to pretty much any cardio as its all about your heartrate. However, it depends on how proficient you are at skipping. Personally, I wouldn't use it as I am rubbish and catch my feet with the rope frequently. The last thing you want when you're in the middle of a high intensity period is to catch the rope with your feet and have to stop - it would defeat the whole object and be extremely frustrating!
Give it a try and see how you get on. Treadmills, ellipticals, stationery bikes, even the swimming pool however, are far more reliable.
Hope that answers your question...
