I’m not clear on what this means. As for Linux system accessing my premium legacy tablo: Firefox, Chrome & Palemoon all still work for complete control and viewing.
Third-party apps including Tablo-Tools, APL Tablo Client and lesser degree Capto for Tablo (CLI Grabber) all continue to function via my Debian system.
I don’t mean to discount your work. Yet it’s a bit futile, work on a discontinued device. I do understand, the tablo UI doesn’t quite let me do what I really want.
Now the newest firmware block direct access via http://tablo/:18080/pvr is disappointing.
Just you seem to suggest Lunux users are 
SOL, which is a bit misleading.
