Yes, that is exactly the concept, a parallel unencrypted broadcast 
network that everyone in range on the same channel can participate in.

802.11s looks like it will be pretty awesome when it exists, but for my 
usage case it's a feature that this transport would be broadcast-only, 
with no station IDs and no routability and work on today's stacks.
