The only serious browser detection is no browser detection at all.

I advise you to read http://www.quirksmode.org/js/support.html for reasons 
not to detect browsers at all.

Parsing navigator.userAgent is the *only* reliable property for performing a 
browser detect (though you never should perform one). Objects aren't going 
to help you.  See http://www.quirksmode.org/js/detect.html for the principle 
of browser detection (which you shouldn never use).

My advice: forget about this project and spend your time on useful things.
