I dug around some more and found this:
ErrorDocument 404 /404.html
RewriteEngine On
RewriteCond %{REQUEST_URI} \.(php|gif|html?|css|jpe?g)$ [NC]
RewriteRule . - [L]
RewriteRule ^([^/]+)/?$ Vendors.php?name=$1 [L]
This does in fact do:
From: http://www.mydomain.com/Demo
To : http://www.mydomain.com/Vendors.php?name=Demo
Now I don't have to micromanage thousands of little folders, but one
database *evil laugh* mwahahahaha
