I read someone saying the bandwidth is costly.

Well… OS could also mean open source, or operating system, and still work well enough for an acronymic moniker.

pmos - Memorable as akin to CMOS, except it is a Package Manager for Open Suse.

Maybe checkout kdirstat (gui) and ncdu (tui)

Because sometimes I would rather things be slow than blurry, and my workstation monitor is >1080p.

We really need to get past the 1080p barrier. AFAICS there is one economical KVM solution for that, and several costly enterprise kits. Surely the actual hardware cost/difference per-unit would be quite small now?

There’s a good idea and some real potential here, but it didn’t quite land for me.
