I came across something called Maploco, and imbedded it on my websitesite.
It offers locations of vistors and put dots on a map as well. Have any of you tried this? Is it accurate, and if not can you recommend something similiar?
Hrmm, not sure if I have seen a map application that is exactly what you mention, but you might check some of my Delicious bookmarks.
What you describe kinda sounds similar to what Yahoo! FireEagle does and/or can do.
I am always on the lookout for more map apps… Seems like the technology changes month-by-month. If you find something cool, please post a link here!
Cheers,
Micky
