gnucap already takes commands from stdin and writes to stdout.

A is not necessary, just connect the in- and output to nc (see NC(1)).

something like
machineA$ mkfifo p
machineA$ gnucap < p 2>&1 | nc -l -p 12345 > p

machineB$ telnet machineA 12345

should do the trick (my first attempt failed, is there a bug?!)

B is implemented in gnucap-uf, but its use is limited.

probably you want to output binary data. in that case you should
consider implementing output plugins, see [1]. i wanted to do that once
to streamline my sock command and to simplify qucs-interoperability,
but i didnt have the time in the end.
