> Finally, I would be very interested in getting the interface to call binary executable running again: it would allow bringing in many other software tools into JIST. So far, I have found much enthusiasm for the pipelining system here, but very little enthusiasm for having to drop all the tools they know and use to be able to work with it.

With regard to the external interface, I would be in favor of something simple even if it doesn't cover all possible cases. I think a good example would be to be able to handle FSL modules, as a good proof of concept (I'll add Lipsia / Via support as soon as we have a basic framework).
