Last week I spent quite a bit of time working with Darren setting up Project Distributor at a client site and figuring out how to integrate it with Draco.NET and NAnt. In the end we built a custom NAnt task which given a username and password, group, project and version can upload a file and have it appear. It works really nicely.
Darren has just uploaded a new version of the Project Distributor code-base!
