Due to the design of the Internet, very few people would know how to run such a service, and due to how most people are, very few will know how later on down the road either. Unless things change and there's a dummy web service where people can just install it like a web browser and not have it open up a ton of security issues, I think it won't change much. The "buzz" of the ecommerce stuff is over and company's aren't online like that used to be, once they found out it doesn't make any difference for most businesses to be online (other than to waste time and money), so I think other than the lack of interest, it'll be the same. I personally don't see much of a change any time soon.
