Hi Shane,
Yes, I'll re-run the course. I'll be away for a couple of months too, so it'll likely be in October or November.
I do teach some libraries. It takes me time to develop courses, so for something like jQuery or MV* frameworks where there's more demand, it's easier to justify the time writing a course. I'm not sure about D3 though! I'm scared it'll just be a one-off.
Another option is to persuade someone to make it the subject of say a Meetup and give a talk. If you haven't found anyone after you come back, give me another shout and I'll think about it! :)
Cheers,
Peter
