A friend at work was just explaining this to me yesterday. I have not tried this myself but some of her tele-action shots looked pretty impressive to me.
She, claiming that it's fairly easy, explained it to me like this:
Step 1. Take a "Burst" of shots using a tripod. It's important that the camera doesn't move at all while shooting.
Step 2. In photoshop, use the "Layer Mask" tool to combine the image. Maybe it was "layer merge"(?).
Step 3. Impress your coworkers.
It should be noted that I know next to nothing about proper photography technique or software but her pictures looked comparable to the one you presented. I'm sure other photo editing software can be used in a similar fashion.

Get 3 identically dressed nordic skiiers and put them on a downhill slope?
Stagger Lee is right. In Photoshop for example you can put each image on its own layer. The first image would provide the background and the first action frame. For subsequent action frames (layers), you have to mask out everything except for the outline of the figure and any other "action" you want (like flying snow for example). AFAIK there is no automatic process for this, though I'd like to hear otherwise if there is any software (or camera for that matter) which can do this automatically. The way I've done it is to start with the magic wand to get close to the selection you want, then manually refine it.
