Why not a directory structure like this:

  /
  |- trunk/ {or in your terms... development/ }
  |- staging/
  |- production/

So you merge change sets from /trunk to /stage, test the system and if
successful merge the change set from /stage to /production

Sound good?

As I'm sure you know, tags are just copies of a file. The tag itself is
the directory that the file lives in.

You would probably want to limit who has commit privileges
on /production but other than that you checkout/export the proper
directory to test that code.

$ svn co ${SVN_ROOT}/development/

or staging, or production

You need to `svn merge -r100:110 ./development/ ./staging/` your changes
from development to staging to promote the code.

Read the section on merging to figure out how to do that from the book.
It's pretty straight forward.

I don't know.

Hope this helps.
