Because most of us have multiple personas, Groove enables you to present yourself differently to different groups of people with whom you're working or communicating. But many organizations have spent hundreds of thousands or millions of dollars investing in the assignment of unique or distinguished names for their employees. Thus, everyone at BigCorp will know exactly what everyone else is called, and there won't be yet another redundant namespace to deal with. In dealing with security issues in Lotus Notes for something more than ten years, I learned a number of important things about cryptographic implementation. Just when you think that you've dealt with an export issue, you run into an import issue.
Nothing is static.
In time, almost anything that we have confidence in today will at some point be questioned or questionable. Finally, there are issues of customer preference. For whatever reason, some customers choose to standardize on specific security vendors, algorithms, implementations, and so on. By designing our product to enable a variety of plug-in implementations, and by enabling a number of them to be used concurrently, we feel that the architecture has more than enough flexibility to carry us forward through many years of service for a wide variety of customers worldwide. Groove cleanly separates the notion of personal identity and device identity.
