The iPod touch and Android apps are also nice. They don't have the live-TV feature, though. One question to Isaac, does it work on neighbor's WIFI setups or on Optimum regional WIFI setups?
It looks like the ap checks to see if you are going through-Cablevision and through-home. You might be able to fool it with a VPN tunnel, but I haven't tried it. The VPN (virtual private network) would involve a VPN-manager on your home network accepting a VPN-tunnel request from another devices somewhere else on the Intranet. VPN tunnels are not trivial to set up, though.
