I read it as a stricly recieve-only solution. For example, it could be desirable to recieve incoming UDP data streams, while maintaining NO possibility for return traffic. However, TCP (and therefore, 99% of Internet application usage) would be impossible by its nature of requiring two-way communication.
A "receive-only" solution isn't quite possible from a network PoV, not only for TCP, but for UDP and other protocols as well. If you allow only inbound traffic, then how are you going to send out the initial request? If you allow only outbound traffic, then you can send the initial request, but won't be able to retrieve the data.
