I'm back from family leave. The baby and mom and doing great, and we have no end of pictures. We've even started a site on Kodakgallery.com just for the family and friends. It's a much simpler way of selectively sharing a large number of photos with a group of people, although not quite an open social site. It's more of a private portal per owner. I think this used to be Ofoto before Kodak reopened it under their brand name. Unlike Flickr, it doesn't openly share pictures with everyone, but each site has its use. In fact, the better way would be to have both visibilities (public and private) through proper access control mechanisms, and let the owner figure out what they'd like to share.
Anyway, I found this article on Tom's Networking on building a Bluetooth sniper rifle, where you can scan open bluetooth devices from hundreds even thousands of feet away, all built from common parts for a few hundred dollars. So, if you have bluetooth cell or laptop, please make sure you try to keep it secure.
