We had enabled the map functionality in our member directory until someone pointed out that it was a huge privacy concern. I think this could be addressed with a couple of things, but I can only figure out how to do one of them at the moment.

• Limit the zoom level in the map to prevent viewing street names
• Prevent the member's address from showing when clicking on the icon on the map (or potentially even the name of the user)

I have a patch for the first, although it would be nice to be able to set the defaultZoom and maxZoom from the web gui rather than hacking Google.tpl

Any suggestions for how to implement the second? I suppose I could remove all references to address in Google.tpl, but it would be a lot nicer if there were some privacy settings in the web interface or this could be blocked by ACL. As it is a member currently cannot view another member's information via. Civi, it's a bit disconcerting that it is exposed on the map.
