Okay.

Great picture. I like pictures.

Step 1:
It would be clearer if you order it:
- COMPLETELY separate sites
- SHARE users ONLY
- MIRROR sites
What about the option of using a different database for each site? No 
need for prefixes.

Step 2:
I would supply a table here to make it clearer:
site:                            directory:
www.example.com    /sites/default/settings.php
sub1.example.com   /sites/sub1.example.com/settings.php
etc.

Step 3:
What I do is: let Apache point to a different document root for every 
hostname, and let each document root be a symlink to the drupal 
directory. This is quite easy and gives you enough flexibility.
