Hey Guys!
I recently did 4 tutorials on texture sharing.
I thought I'd post them here so you might all learn from them.
4 x videos
This is an exciting post! 
Thank you very much for the fact that this topic is greatly undervalued or not given enough attention by many users, as Spout/Syphon is a great way to expand Arena/Avenue with content and footage, often at no cost (with:
- Desktop ISF Editor -
https://isf.vidvox.net/desktop-editor/ with massiv ISFs as +contents
- NestDrop V2 -
https://nestimmersion.ca/nestdrop.php/ with massiv MilkDrops as +Footages
- TOOLL3 -
https://tooll.io/ to expand the spectrum off U artworking
- SMODE Community -
https://www.smode.io/en/product/community-visual-art/ to expand in all
- And so much more if you take a look at the Spout page, for example -

NDI also has a lot of benefits in my opinion, although I see this more in the ability to easily connect outputs to individual monitors or LED panels over long distances via a easy network cable (and control them selectively).
But fundamentally I would like to stress that I only consider Spout/Syphon implementet direct in the program source code, so I mean for apps where you can find the Spout/Syphon in Arena/Avenue directly in/under the sources without any further action, and just that apps get a real highly efficient texture sharing, as this is the only way that directly uses the GPU buffer and is practically purely GPU-based. & so with a current mid-range GPU, a lot is actually possible; the frame rate does not collapse when 2 or 3 texture sharing sources are used under K1 in Arena/Avenue.
I'm a bit pessimistic about NDI or Spout/Syphon-screen-capturing, as the CPU usually has to do most of the work there, which usually leads to poor results on average consumer computers.
You should also never forget that screen capturing for perhaps for K1 requires an additional 1920x1080 free work-monitor area for that self. Even if a window can be selected, it must be open and will be transferred in the actual & current dimension via Spout/Syphon during screen capturing, etc. With a truly implemented spout sender in an app, however, this app can run on any virtual desktop from the work-monitor/OS and still arrive in K1 in Arena/Avenue perfectly.
But that's my practical experience; perhaps others have diffrends and let me know.
