Build server licensing

I’ve purchase a single developer licence which allows me to compile code without the water mark. However, we deploy assemblies (including XAPs) that have been built on a separate build machine so my question is, should I be installing the license on the build machine so that the correct key is used?

No, it’s not necessary to install development licenses on build machines for GoWPF or GoSilverlight.

(But it is necessary for GoWin or for GoWeb using the web site project model.)
