Wikitude browser question

So im still alittle fuzzy on the whole idea about what the wikitude browser is but from what i understand, it uses your location or the view finder of your camera to help you locate and identify your surroundings.

So my question is as far as wikitude working with BBM.
Can you and will you be able to see peoples pins around you? and will it only recognise people who are using new blackberry 7 devices that support the wikitude browser?

Any concrete info or user experience would be helpful.

Thanks :)
