I can add that by default (for a Norwegian install at least), Excel exports CSV files with semicolon which makes them a bit tricky to import for Vuo. Maybe the separator list for the Fetch Table node should be expanded, or replaced by a custom separator instead?
Edit: This is based on a regional setting in the OS, but changing this will break other stuff, so I'd rather not deal with it. I can also see issues with tables exported and sent across different countries.
Just remember to have proper network infrastructure if using NDI. With overhead, you can't run too many 1080p streams on a 1Gbps network before you hit a chokepoint. 10 Gbps (or 100 if you have a very spacious budget) is preferrable. An alternative to the Magewells and BM Video Assist is the BM Web presenter which is a SDI to webcam solution.
