At a minimum I foresee concatenating input files with it. My current project has 350+ video files. Avisynth cannot work with more than 25 - 35 without crashing. I have not found an Avisynth mechanism for concatenating files that preserves audio.

To avoid intermediate storage. Workspace for this project is 2TB. Each additional version of the project is currently ~700GB. Some form of inter-process communication is required to avoid intermediate storage. TCPSource() seems the only type of built-in IPC input Avisynth supports.

Thanks, I have been using that for other purposes.
