I was just writing a website with some javascript, and was dealing with the different browser stuff. Basically, there are a bunch of rules to tell which browser is being used. I am sure that it can be done, hiding the browser name and all. Maybe a prompt to ask for the details so that you can change it every time you open the browser? Until they force a browser to identify its self by one of the major brand names, you could put random stuff in there to fool it.
