The SSH protocol has a way to do it, through
SSH_MSG_CHANNEL_EXTENDED_DATA packets on a channel otherwise sending
some other type of data.

libssh2 has a handy libssh2_channel_read_stderr() macro.

How generic must this be on the server side? If you control also what
is running on the server you could use a separate channel for the
status updates. It could exec or open up a subsystem or even a TCP
connection from the server side. (See the direct_tcpip.c example.)
