You almost make it sound as if it could be done if you didn't care about scalability and "nice to haves". Make me the site he described, and have it work for only 1 user, even half the time, and I'll give you $1000 gladly.
I could do that, please specify where you are going to click and what you'd expect to see. It will work every time but only for those exact steps! Scalability could be done but will cost you extra!
