Just discovered a website called Teachem.com that allows a person, organization, or business to repurpose instructional videos it has posted to YouTube. It's easier to show how Teachem.com works than it is to explain it, so below I've posted the Securifi Almond Range Extender Demo I created in the Fall of 2012.
As you can see, once you've created the "classroom" version of your video on Teachem the site provides embeddable code you can insert into a blog page:
Beyond that, Teachem lets you start a virtual school by aggregating your courses in a central location and branding it with your organization's logo. You can also take advantage of YouTube's versatility in allowing private videos to be uploaded; in such cases only those who enroll at your Teachem school can view and consume your content.
It's an interesting idea, though at the moment, because it's free to register at Teachem (and just as free to create courses with anyone's YouTube content -- not just your own), it's unclear what kind of revenue model the site's creators envision for it.
