I've found a number of 'Hotspot-in-a-box' units have a feature marketed
as 'inter-VLAN security'.  Essentially, with this enabled, STA's only
see traffic to the AP & back, not other STA's (associated to the same
AP).  

Funky indeed, 'security though obscurity'.  I haven't broken out a
802.11 frame sniffer (yet), wondering how this is technically done and
expierences deploying this?  It would seem like all the Hotspot players
would jump on this, as a "security" solution.

The most 'famous' box, seems to be Handspring's WSG-4000 (relabeled from
ZyXEL, DemarcTech, etc)
