Wow Kevin, from your last post I'd swear you were kidnapped and replaced by a real estate agent with a thing against videographers!

My opinion has always been that whatever photos can do, video can do 29.97 times better every second. But then, as a videographer who doesn't touch still photography, I am a bit biased.
The project you were doing doesn't really sound at all like the sort of real estate video project that the article was describing. The last time I shot a real estate video (admittedly it was a while ago) it only took me about 30 minutes to tape. Well, I was there for probably more than an hour, but I spent half of that time talking to the neighbor about our company, so that hardly counts. In a few hours, I had the walkthrough complete and ready to send to the real estate agent. It wasn't a lot of cash, but the $350 I charged for a whopping 3 hours of work (total) felt pretty good. Compare that to the 40 or so that goes into a $2,000 wedding, and real estate video looks far better on an hour-by-hour basis.
And when you say that there's not really any reason for real estate video, you have to keep in mind that there are a LOT of people who feel the same exact way about wedding video, and we all know those folks are wrong, don't we? Just because you personally don't see an interest in it doesn't mean that there aren't a lot of potential homeowners who wouldn't love to get a virtual walkthrough before they packed up and drove across the country to see the house in person. And where photos are nice and all, they don't convey the spatial boundaries of a room the same way a video moving through the house can. A picture shows you what a room looks like, but you're not going to spend your life sitting in a corner looking at the rooms in your house - you're going to spend your life walking around in your house. Sure a picture might give you an idea what a room looks like, but a video will show you how it feels to move room from room, and gives you an honest appraisal you can't get from photos alone.
Anyway, I don't know why I'm making a case for real estate videos. I don't do them, and I doubt I'll ever have the gumption to go out there and wrangle up the business to do them. All the same, I see it as an interesting medium that might indeed be fun to produce.
At the very least, I do agree with one thing you said wholeheartedly.
if you want to make money in real estate, buy some.
Cheers!
