This is a really neat concept that I think would be fun to use. Looking at the usage, I thought this syntax was interesting: //here's how we read a key $sx->readKey('username', $username); Is there a reason you are requiring a variable to be passed by reference to the readKey function, instead of doing: $username = $sx->readKey('username'); EDIT: ahh, I see you have a returnKey('key') function that works that way
