What are you trying to gain by creating two different ways of how
the admin area is handled?

In your proposal, the top-level .svn directory mirrors the working
copy anyway, so your goal cannot be to improve performance.

Performance would even be worse in some cases, because if you move
a directory you'd have to keep the tree in your global .svn directory
in sync with the working copy state.

I recommend you read the subversion/libsvn_wc/README file if you
have not read it already. It explains a lot of the reasons behind
the current design. Some shortcomings of the current design are
documented in notes/wc-improvements.

AFAIK the idea of a global .svn directory has been coined before,
but more in a context of a general working copy redesign/rewrite,
instead of adding additional complexity to an already complex
library -- libsvn_wc is, at least according to Karl Fogel and Michael
Pilato who told me this in person, one of the most complex areas
in the subversion code that few developers want to mess with.
