The interesting new feature is that the networks parameter is simply a set of key-value pairs, and you can use anything as the key. So instead ofmac_address, for example, you could pass a GSM Cell ID, or a Bluetooth Device Address.….  

Once I’ve done that — gluing the Bluetooth Device Address, using the key bd_addr to the Plaze — I can now build a mobile application that scans for Bluetooth addresses and queries Plazes 

 

This is where it gets more interesting as far as Roomware is concerned, their method of using these keys as identifiers for presence could serve as an interesting use case for our own implementation of this sort of location ‘mapping’. One simple Roomware example we often talk about is using a batch of Roomware servers to act as Zones for a location for instance. Whenever someone is near one of the Roomware servers they are detected and can be placed on a map which can then be used by other applications to make a friend locater at large events or a historical timeline of visitor activity.  It’s nice to see some more working implementations in this field and maybe even the start of some standards for working with presence and network identifiers.
