I've never heard of eTrust or any such software, so I can only imagine that LabVIEW does not have any explicit support for such a product. The more logical question seems to be if this product somehow supports LabVIEW or similar applications. If you are wanting to keep track of developer activities, you should consider using a source code control provider. This will enable you to track all modifications to your code base and keep previous versions of your code.
