a true history of wayback web browsing

so i live and work in about 6 places right now (2 labs in Paris, plus apartment, 1 London, 2 Cambridge) and typically am not in any one for more than a few days at a time. Flipside is that it is sometimes a few days between visits to any given place - so I tend to leave myself logged in (perhaps lock screen) on a Mac at each place - and so when I next show up, I have a bunch of tabs or windows open on activities that are a few days stale - e.g. news.bbc.co.uk, my facebook account my gmail account, a hotmail spaces and myspace - so on each of these, i see a snapshot as of 3,4,5 days ago - fascinating stuff - espeiclaly to se lcalization (sites dont show same thing - depends on your locale yur client ip address reverse looksup to...)
