I just heard about the wikalong feature today and am still trying to wrap my brain around what it could mean. To quote the Firefox people:

Too cool, way too cool. I'm really interested in your ideas: how could this technology be used in education or IDT?
Here's a screenshot of what wikalong would look like:
