I think you are right in assuming that the buyer side of the market is not going to consist of developers. However, there is certainly a market here if the right people are targeted and the projects are presented as businesses in a box as opposed to abandoned side projects.

Potential buyers include MBA's who can't code, or don't have time to, and all of those many people who tell you "I have an idea I just need you to build it and we will split everything 50/50". If the grand vision was presented to them properly, they just might shell out a few thousand for it.
