Hmm... i think you all are looking a bit too hard into this. frames... remember HTML from back in the day? 😛 (pls dont ravage me im just funnin)
if you set frames than the ONLY address they will see is 'www.yoursite.com' they can click on links all day and never see them in the address bar. unless you do some java they will still see them in the bottom left (with IE) when the move their cursor over them. but just find a page that has text scrolling down there, view the source and copy the javascript to do that. change it to what you want it to say and NO ONE will see the URL to the page they are on, or going too.
