A 404 not found is not something that a server usually spits out when 
you have merely given it the wrong information. Error, Access Denied, 
Authentication Failed, something, but not a 404. So I strongly suspect 
your URL is wrong. Try https? (though that would mean using Net::HTTPS 
instead of Net::HTTP). One strategy would be to find something that 
successfully connects to Google by this method (if you have a working 
example in another language, or even a binary file), you should run that 
and sniff your own packets to see exactly what is being sent. 
"livehttpheaders" is a Firefox extension that I use for this sort of 
thing, if there is any way for you to use a web browser to log in to 
this google authentication thing.

Good luck,
Dan
