Ask HN: How can I self-publish talks like InfoQ? (Software question)

There was a recent submission to HN on a talk Rich Hickey gave. It can be found here: http://news.ycombinator.com/item?id=4173854

Once in a while, I give presentations at local meetups. I would love to be able to pre-record my presentation, and post it on the web in the sort of format InfoQ uses.

I'm referring to the format whereby a slide deck advances along with the video of the speaker. Are there any off-the-shelf software packages that have this sort of functionality?

Thanks!
