Oh dear - 2008 is going to be busy.
Take the open source development methodology, mix well with enlightened self interest, stir with companies that have the dosh to fund serious development, and you have a really compelling business model. We're referring here, of course, to Collaborative Software Initiative (CSI).
CSI launched in early 2007, the brainchild of Stuart Cohen (formerly CEO of the Open Source Development Labs, which merged into the Linux Foundation in 2006). Its business model is to use the open development model to create necessary software for niche markets. For example, CSI's most recent project is creating software to automate the BITS Shared Assessment Program for companies in the financial services industry.
While it's unlikely that a community would spring up around this sort of software naturally, CSI is using the open development model to create software needed by industries and letting several companies split the development costs. Its role is to do the collaboration and community building, project management, tech support, and foundation building necessary to shepherd the software through its life cycle.
This is an idea that should have been obvious years ago, and we expect to see the CSI do well in 2008-- and attract copycat initiatives as well.
Update I liked the way it read so much that I put it in the post.
