Scanning for beacons w/in a web page

I appreciate the privacy reasons why the current BLE approach is to connect
to a single device and talk only to that device.

However, for the physical web project, we'd also like to figure out a way
to support ''the museum scenario". In this case, all of the exhibits
broadcast a single URL, the 'museum app' which displays the overall museum
experience. However, it can also show what exhibits are nearby and give you
info as you walk through. It could even connect to exhibits and make them
interactive.

The purpose of this example is call out the need for a web page to work
with a collection of related BLE devices, not just a single one. My concern
is that the current one-at-a-time approach that is being taken, while
secure, is preventing this scenario.

Is there a way we could ask the user for an additional permission,
something like we do for geo-location, so the JS could then scan for a
family of beacons?
