Using the feed in a dhcp enabled local network with a simple access-list would solve the problem you are talking about. Any good router have support for ACL.
Before emailing CISCO, you could have made a through search in their site. Then the solution would have come right in front of you.
Have money to afford the solution??
Get a real AP like Cisco Aironet 1550 series CAP1552E.

who said that? :rolleyes:
@OP: It's not a rocket science.
Use local network to distribute the feeds, via wifi or LAN.
Use two good N300 routers if you plan to use wifi.
