I'm able to add users on the Site Admin menu and assigned them Admin rights (or should it just be Editor?). I like for each user to have complete access to their blog (and ability to add sub-users to their blog) but not able to access/manage other's blogs/sites.
Secondly, on the htaccess rules and mod_rewrite portion. Do you mean to create specific category for each user, assigned them as admin/editor? and then using .htaccess and mod_write (especially mod_rewrite) to point/forward the category links to the higher directory?

For Apache Hackers
The following list gives detailed information about the internal processing steps:
Request:
/xyz/oldstuff.html
Internal Processing:
/xyz/oldstuff.html -> /abc/def/oldstuff.html (per-server Alias)
/abc/def/oldstuff.html -> /abc/def/newstuff.html (per-dir RewriteRule)
/abc/def/newstuff.html -> /xyz/newstuff.html (per-dir RewriteBase)
/xyz/newstuff.html -> /abc/def/newstuff.html (per-server Alias)
Result:
/abc/def/newstuff.html
This seems very complicated, but is in fact correct Apache internal processing. Because the per-directory rewriting comes late in the process, the rewritten request has to be re-injected into the Apache kernel. This is not the serious overhead it may seem to be - this re-injection is completely internal to the Apache server (and the same procedure is used by many other operations within Apache).
