Hello Marcus,
hello Kevin,

thank you for your hints. Meanwhile I also recognized pmt::serialize, which I 
found awesome. And Marcus pointing to ZeroMQ was even better. I will try both 
and report back.

Mit freundlichen Grüßen / Best regards

Hi Stephan,

have a look at the ZeroMQ blocks (ZeroMQ, including the ZeroMQ C++ wrapper 
header will need to be present at compilation time); The ZeroMQ sinks have the 
option to pass along tags!
ZeroMQ is a world of its own; if you want a single point-to-point connection, 
try the REP sink and the REQ source, with an address like tcp://<ip address of 
your computer>:5555 in both.
If you want a publisher/multi-subscriber thing, have a look at the pub/sub 
combination. There's examples, typically in /usr/share/gnuradio/examples/zeromq

Best regards,
Marcus
