Sounds like a first step towards mOS.

These databases you speak about are what in mOS is called "OID servers".
It's just that the kernel doesn't take care of it, except for a very small
part.

Yes it's much like what's been discussed. Maybe even more that you think.
I've written an introduction to mOS for the web site. I think you'll find
much there that corresponds to your ideas. And you maybe even will find
yourself agreeing on it. :)
