Recently it was proposed on the DotGNU developers
mailing list that "DotGNU" should be interpreted as a recursive
acronym (like GNU stands for "GNU's Not Unix").. so maybe it will
turn out that "DotGNU" really means something like "DotGNU over the
GNU Networking Universe". In any case, we're building something
that could be called an "operating system for the internet" - a
collection of tools that allow software components to interact with
each other over the internet.
