The technical details (pipes or dynamic or static linking) aren't what makes the exe a derivative work of Octave or not, but rather the fundamental nature of the communication and the kind of the data exchanged. For example, is your exe producing output that only Octave would understand and is only meant to be used with Octave? If so, this is a GPL violation. What kind of effort would it take to make comedi support your NI hardware? This is the real long-term solution. - Jordi G.
