roles in the Pear DSN

Hello, This is my first message to the php.pear.dev group, so first of all I'd like to say I have found it incredibally usefull and some of the best php code I have worked with. Which brings me to my next point. It was fine up until I realized I was going to need to have users log in with different roles (using interbase), anyway I went ahead and changed the ibase.php and db.php files, both of which I found very readable and simple to alter with out changing coding format etc. It works for interbase, but I have not yet tried roles on mssql or oracle. I was just wondering if it was worth me adding role to the DSN or not? I modified parseDSN so that it looks for the role after the password i.e user:pass:role ... Are there allready plans to implement roles into the DSN or am I missing something obvious as to why it doesnt allready? thanks -shaunXcore
