How long until we see *this* cool gadget at WDW?

Check out this cool new add-on stroller gadget. It's essentially a bike that hooks onto your stroller, and you can use two of them, so that a single stroller will haul 3 kids if the parent doesn't mind being a little squished in the middle.

I wonder if WDW would allow these in the parks? It's not exactly a stroller, but it's not a wagon, either.

Time will tell if they catch on, I guess. They are not available in the US yet, but they looked so interesting I had to post.
