Zooming the map is technically not too much of a problem. Having said that...
People can choose to advertise their rough coordinates to others. The coordinates that members provide are currently used to provide astronomical information and to calculate line-of-sight distance between two members.
The current member map does not broadcast the exact coordinates of any member to anyone. A map that displays coordinates of people becomes a privacy issue when the same coordinates are used to display their location on a zoomable map. Simply because their coordinates are open for all to see when using an interface that runs in a web browser.
I have written a couple of zoomable maps but they will never see the light of day in their current form. In the end, any public map will only display a limited number of members. ie. Only the people who have opted to be shown on a map. Which will make for a very boring map.
It's been a while since I've looked at that map. That's a lot o' dots!
