This all seems like a perfect case for the singleton pattern. See

Im currently trying to wrap the brain around the Singleton Registry 
article.
Wish me luck :)

This is based on work seen at 
http://www.phppatterns.com/index.php/article/articleview/75/1/1/
Yes yes, I know.  It uses $GLOBALS, (OO Sin).  Father forgive me....
From the article, Im getting lost with the reason/meaning/purpose of 
the instance() method.
If anyone can clarify it for me, and let me know if my example would 
need something like it.
So if you care to critique it, feel free, Ill try not to be hurt ;)
Thanks
