I think the interesting point to look at is the 'traditional' non-university institutions teaching university-like courses (Nursing, IT, etc.). They tend to move faster then anyone else because of size and their economy is more straightforward in most places. They provide education & accreditation in exchange for tuition. For this reason.

They are moving towards self paced learning via the kinds of 'modules discussed here. They still have buildings and teachers (standing around or answering questions). But the distinction between this and online schooling is much harder to make.
