Right, it's another possible candidate for true high bandwidth "wireless wires" for applications like uncompressed video, external PCIe, high speed data access etc. Wearable displays are the most obvious candidate, it'd be very useful to be able to have the bandwidth on tap to perfectly replace DisplayPort/HDMI/Thunderbolt for 8k+ video while in an office, along with access to office NAS/SAN and potentially seamless use of other peripherals like GPUs. That would mean a wearable display could potentially function as a true no-compromise monitor/system replacement, and then transparently downgrade to independent mode when leaving. As you and others say that could even be an extra security advantage, that while sure there'd absolutely be authentication, it'd be an interesting capability that only a given light cell in a given room/cubicle/area could access particular VLANs or the like at all. The range being short doesn't negate the benefit of no wire, nothing to snarl or snag or get forgotten about. And the backbone aspect seems to be coming along as well. 40/50/100G is becoming surprisingly affordable even now, and in another 3-5 years as this cooks I don't think it'd be a blocker even if it was high end for a solid period of time like most new tech is. There are other potential approaches but WiFi+LiFi hybrids could be neat. LiFi would also have the regulatory advantage of not needing to worry about typical licensing or bandwidth issues beyond basic emissions like anything with a power supply has, since those spectrums are of course fully public :). Although the industry could in principle muck the whole thing up with burdensome patents I suppose, but then again the basic principle are similar to fiber and free space optical transmission (including extremely high speed) has been done for ages so that might limit the scope of any potential claims to some degree.
