JVN,
Sounds like fun! our team already puts a lot of effort into documenting every meeting and event on our blog:

The hardest part looks like publicly documenting what you are working on without giving the idea away. If someone reminds me I'll try and put it all together from the blog posts at the end of the build season, I remember following your facebook posts last year during build and trying to figure out what you guys were thinking.
