Maybe ncat can have a "--udp-tunnel" option as an advance of the "-k" ?

When used like:
ncat --udp-tunnel -l 53 --sh-exec "minibill@89.16.178.89 \"ncat -u 8.8.8.8 53\""

It will start and keep the connection open, and consider any incoming
connection as if it was from the same host.
This can bring problems it two clients connect and send data at the
same time, but it is the same as of broker mode.

Does anyone think this is useful?

Regards,
Nuno
