So in essence, you're motivated by the same underlying concept as the Plan 9/Inferno developers: define a small set of abstractions and apply them ruthlessly, in contrast to the myriad of non-uniform interfaces one is practically using every day in an operating system.
For Plan 9, it was "everything is a file" and the power of using simple operations like bind mounts to create complex software interactions that would otherwise require monolithic protocol and library stacks anywhere else.
Here, it's... "everything is a table"? I'm not very familiar with table-oriented programming, but what advantages does having the RDBMS be the prime metaphor over the file system really bring? Structure? Rob Pike had some interesting words on that: http://slashdot.org/story/50858
