How about a different approach all together. Create an incubator where people register their ideas, talent and available time. Ideas get categorized and weighted then voted upon. Weighting is based on the supporting information to the idea: product spec, site, code, etc.. The ideas are voted on for feasibility and a range of factors and then get an execution plan built. A plan based on tasks, resource needs, etc is put together, and then member of the site can get coupled to an idea to contribute a specific amount of time to a project and a specific set of tasks. If all the ideas are web-apps, the people who register as "designers" can produce UIs for hte ideas, DBAs could develop schemas, etc.. etc... Members can work on multiple projects - and get % equity of each idea they contribute to. A whole range of incentives/disincentives could be setup. The fund pays for milestones etc... and as things spin up for certain ideas, they can spin out to more traditional company setups... This is basically to put out MVPs for given ideas and match those ideas with the appropriate skills of the membership - everyone has a stake.
