Chef hangout is pretty much what you described. It's a live video lesson using Google Hangout. I haven't done it but hear good things.
Also I think a lot of what you want is just being taught the basics. Many of those you can pick up just from a video or in some of the simpler cases even a text description. Your oil (preferably canola if you're cooking with it, olive has too low of a smoke point and is better suited for other uses) looks a certain way (sorta shimmery) when it's ready. Once you know that it's pretty much the same for every recipe.
Some a chef would have to be present for. I don't think you can tell by sight when the alcohol has evaporated when cooking with wine, you just have to smell. You can't tell by sight when meat is done or a bean you're blanching is crisp-tender, you have to touch it or bite it.
For that reason I don't think online instruction will ever totally negate offline the way it can in many disciplines. But it definitely can do a lot better than it is.
