Just a thought for a way to boost Confluence's sales.

How about having a free 'personal edition' which comes in a simple to install, only runs on local host, Confluence system which allows folks to use Confluence as a personal documentation system for todo-lists, ideas, thoughts, proofing blog posts etc.

If I had Confluence on my laptop for example I can imagine using it all the time for notes, things I should do, personal ideas and so forth.

Then this could act as a loss-leader, get folks hooked on it so they get their pointy haired bosses to buy it at their day jobs when working with teams?
