We got several interesting submissions, but we had to choose one...
The proposal from Matt S Trout / Shadowcat convinced us. The technical part looks very promising (and we're honoured by a core Catalyst developer coding an app for us), but the social aspects of his proposal is what set it apart from the rest:
Shadowcat would like to defer the bounty to fund additional Catalyst or DBIC related WoC projects. This means we get twice the value for our (your!) money. Additionally, they want to put the app in the Reaction repository under a perl license to serve as an example of Reaction development. Which makes this effort even better, because good, real-live example apps are very valuable when learning a new technology.
Matt plans to implement the system over Christmas, so if everything works out as planned we can start with the TODO test bounties in Jannuary.
Thanks to all the sponsors and attendents of YAPC::Europe 2007 who made it possible for Vienna.pm to fund this and other projects!
