You wouldn't carry a fbx around a mall -- needs too much electricity.  
you do carry a cell phone -- everyone carries a cell phone, and a mesh 
protocol that opportunistically linked  wifi-enabled smart phones would 
be cool.  There might be a few mall shops running wifi or fbxs that 
could provide uplinks, while wandering shoppers w/ fbx-phone provided 
extended coverage...

I don't think this would provide much bandwidth, though.
