How to send a continuous stream through ssh

Question

Given a named pipe, how can I send a continuous stream of this pipe through ssh?

The netcat equivalent of what I am looking for is

• from client

  dd if=myfifo | nc -l 12345
  

• from server

  nc <client IP> 12345 > stream
  

Answer 1

cat source.data | ssh ${hostname} 'cat > destination.data'

Alternatively:

ssh ${hostname} 'cat > destination.data' < source.data
