This sounds interesting Locoweed. I am tempted to jump in with both feet but am starting school full time + full time work. However if you are going to guide the product along with fellow crusties then it seems too good to pass up. I'd be interested in something like a 'level designer junior' - a sort of understudy- or some similar if it turns out that others have similar time limits. If a list of structures or plans for a level are drawn up then as time allows I could do some grunt work and build some houses or make terrains etc. I just don't want to be the 'main guy' in any category and not be able to deliver.
Otherwise I'll look forward to the next experiment as this sounds promising.
