+1 for the idea, but you don't have Apache Members there (neither Ian nor Jeff are ASF members, as far as I know).

While there is reliance on > salaried developers (currently from [http://en.wikipedia.org/wiki/NHN > NHN, corp], but it's expected that other company's salaried developers > will also be involved), the Hama Community is very active and things > should balance out fairly quickly.
