There are two license types for PVS-Studio:
You need the license for a team. The reasons are explained in the answer to the question: "Licensing of PVS-Studio: why don't we have Single User License?".
No, you cannot. The analyzer can't be divided.
Yes, a build server is an ordinary computer and it needs a licensed tool to be installed on it as well. Our standard license for a team of up to nine developers can be applied to a build server. If you have several build servers and a large developer team, then consider purchasing the Enterprise License.
The license is a pair "name/value" into which some additional information is encoded (including the date). One and the same license is used on all the computers both in case of the standard license (for a team of up to nine persons) and the Enterprise License.
No - because we have very handy Enterprise Licenses. If you think that you need a floating-license, just have a look at our Enterprise Licenses.
No, they are not. Compare them to Parasoft, Klocwork, Coverity and other static analysis tool developers. But don't compare them to Visual Studio! Even the people from Microsoft themselves tell that their developer tool department is loss-making.
