This would be great in theory. In practice, major devices are hamstrung, like Apple not supporting MST which would enable monitor daisy-chaining.
MST (multi-stream transport) is a DisplayPort thing, which Windows uses. So you have DisplayPort over thunderbolt, and (presumably?) the multiple displays are opaque to thunderbolt. I've used this with thunderbolt/usb3 hubs that understand MST.
On Macs, however, they use thunderbolt's own ability to have multiple devices. You need to look carefully for hubs that support this instead.
Or at least this is my very limited understanding, born of utter bafflement with our work docking stations.
I post this mostly in order infuriate somebody with actual knowledge. Please set me straight.
