2) Is there a build only license?
3) We also used a build machine for official build; do I need a full license here to?

For question 1: Anyone who wants to build an application that includes NetAdvantage for .NET controls needs to have a licensed version of the toolset installed, and each such developer must have their own license. We recommend the build server approach for developers who aren't working on the UI who need to build such a project.
This blog post should likely address questions 2 and 3 in detail. To summarize, any licensed developer can set up a build server, which doesn't require its own license so long as no development work is done on that build server (other than building, of course).
