Actually, no, demos is not the goal. The goal is to make it as easy as possible for anyone, even the overworked part-time sys admin at a K-12 school, to try out OpenACS and dotLRN. The easier it is to install, the more likely they are to attempt it, then succeed, and then use their installation for something cool.
After all this discussion I'm still not sure yet what the best way to accomplish that would be.
