This article discusses an alternative programming model for services that use location information. The paper proposes a new architecture for such services, which does not require users to share information about their location with service providers (services). This architecture is based on the author's proposed network spatial proximity model, where geocomputation is replaced by direct proximity measurement. This approach explicitly assumes that most services, using location information, describe (provide) some local services. Accordingly, geo-coordinates are used only for calculating proximity when searching (selecting) offers. It opens up the possibility of replacing geo-coordinates with direct measurement of proximity. Within the network proximity model, geo-computation is replaced by direct proximity definitions. And it is proposed to form this measurement of proximity based on the physical availability of signals of wireless network nodes, thus building cyber-physical systems.
you can try to use Core Bluetooth devices as tags: http://bdp.linkstore.ru

Check out 411 for Twitter in this connection. Your own code behind tweets: http://t411.linkstore.ru
We built similar stuff with Core Bluetooth (so, any Android phone is Ok): http://bdp.linkstore.ru

It is server-based. Server-less version will be later as I wrote. Yes, it is like chat rooms, it is like client-server and it is like web. There is a web session actually :). We've tested a way for linking (pairing) two devices. From HTML5 there is File Reading API
Yes, we tried server-less system on WebRTC. The problem is an actual support for WebRTC in mobile browsers. It is even less than HTML5. So, just wait for a moment.
There is a conceptually similar stuff for Twitter: http://t411.linkstore.ru
And does it work for iPhone too? non-rooted? We did such stuff as SpotEx: http://spotex.linkstore.ru But Wi-Fi scan on iPhone was a problem.
answers depend on the accuracy in users profiles. Btw, you can try this simple search in your social circle: http://servletsuite.com/fbdir
It does not send SMS automatically. Just open SMS client

you can use a separate app if you need share your search query: http://servletsuite.blogspot.com/2012/02/ask-friends-sociali...
Check out secure notes: http://sn.linkstore.ru And it has got simple API
old trick - Where Are You Now: http://servletsuite.blogspot.com/2010/10/where-are-you-now.h... Send link to Geo Mail
as per use cases: check-ins could be simplified with QR-codes. See http://servletsuite.com/qrcode.htm

I think multiple ID is a working idea. We have used it in safe location sharing WATN: http://servletsuite.blogspot.com/2011/10/where-are-they-now.... And yes, it is good for users but bad for advertisers
http://tinfo.linkstore.ru WHOIS for Twitter
You can see that on the map. Visiting http://wayn.linkstore.ru (on phones with Javascript support) will open the phone's email app with a canned message titled "Where are you now?" and a link to GeoMail in the email body. If the recipient is using a phone that supports the HTML5 location provider API, such as an Android or Samsung Bada device or an iPhone, when they click the link it will launch GeoMail webapp which lets them reply with a link to a Google Map showing their location.
