This reminds me a little bit of the ideas behind Reiser4[1] -- the idea being that we could unify different namespaces of data (files, metadata of files, databases, anything) into a unified namespace which you could then use Unix tools on. It is a bit of a shame that the ideas behind Reiser4 have been lost with Hans Reiser's murder conviction, and nobody has really picked them back up since then. One of the neat ideas more directly related to this talk is that Reiser4 had the ability for users to define their own data layout (I think they were called "modules") which would allow you to optimise the filesystem layout for databases while still allowing non-database software to read the contents.
