Tricky Multi-site config

Actually, because of your question -- i started poking at the DB object more thoroughly.

Looks like there was a plan to (or used to be implemented) accepting a DSN when calling load->database(), however it doesn't appear that it was ever completed (atleast that I see)

You might consider modifying the first line of the DB() function:

Code:

if (is_string($params) AND strpos($params, '://') === FALSE)

to be:

Code:

if( !is_array($params) )

This will allow you to pass an array with the database configuration (hostname,password,username,dbdriver,active_r,etc...) to load->database.
