Ant, Maven, and the JDK are all considered tools by hudson, and as such, their
configuration (such as their path) can be configured per-host, and each can have
different configurations (such as Maven 2.0.9, Maven 2.1, etc).

It would be great if the MSBuild plugin treated msbuild the same way, so I could
configure msbuild differently for each server. For example, on Linux,
"msbuild.exe" is actually "xbuild.exe", and the path is completely different.
