@section One-way broadcasting communications

Sometimes you have got high-bandwidth but unidirectional link, for
example, satellite's broadcasting signal. You are not able to use online
@ref{Sync, synchronization protocol} because it requires mutual interaction.

You can use @ref{Bundles, bundles} and stream them above. They are just
a sequence of @ref{Encrypted, encrypted packets} you can catch on.

@example
$ nncp-bundle -tx alice bob eve @dots{} | command to send broadcast
$ command to receive broadcast | nncp-bundle -rx
@end example

With built-in packet duplicates detection ability, you can retransmit
your broadcasts from time to time, to increase chances the recipient
will catch them by regular stream listening.
