Hi Molly, This is Jock from DealerPeak.com The idea seems pretty incredible but it's not all that difficult from a technical standpoint. We have the same capability on our CRM/Website platform. You see the servers have awareness of where a site visitor comes from, the referring URL. Based on that you can view from within the CRM where those users are coming from. We take it a step further by matching up the site visitor with the information we have on that visitor in the CRM. So you can actually see that "Joe Smith" is now on your website in real-time and you can also see how many times he's visited, how many cars he's bought from you, if he has any active leads with you etc. etc. It's very cool technology and opens up huge sales opportunities if someone is watching it. To my knowledge VINSolutions and DealerPeak are the only one's who have it. We call ours CyberSonar. Hope this answers your question.
