Just to add to Michele's comprehensive answer, you realise of course that the *only* thing you can tell is whether somebody's made a request to your wibstie recently...they could request one of your pages, "move off-site" by requesting another page, then request another of yours, all within your 'visitor' time and you wouldn't know about it.
This concept of being "on" or "off" a wibstie is a confusing one, perpetuated by marketing departments and stats-sellers. Think about your own browsing habits - how often do you 'visit' a whole site, look around for a while, then 'move off' to another site? I generally have 4/5 windows open - a Newest Nodes on 20 minute refresh, a google sitting waiting etc., and at least 70% of the time I leap straight from a search into a single page, absorb /reject, then go back to the search, check out the next page etc...
I'm not saying at all you shouldn't do it - I like seeing 'Other Users' - but you should be aware of the fact that it doesn't mean as much as your PHB's think it does. :)
Cheers
Ben
