Is it a possibility to have OS installations on these things stuffed inside ram slots in the future? Maybe these sort of features and the special ram sticks themselves would only be able to be used by server boards with specific chipsets. Exciting none the less!
Yes, having your OS installation, and all your video files, on DIMMs stuffed into RAM slots is exactly how 3D Xpoint might change how computers work. This would require support in both the memory controller and OS.
I imagine it would be sort of like a NUMA architecture. Some DIMMs are slower non-volatile huge Optane DIMMs while others are fast volatile DDR4 DIMMs and the system has to know which are which and act accordingly, e.g. not using the Optane DIMMs for active running program code and not storing very large data sets on the DDR4 DIMMs.
The 6TB was with a mix of DDR4 and Optane DIMMs, you still want DDR4 for both its endurance and speed, so the Optane DIMMs will have to offer more capacity than 256 GB.
What this means is that a mix of DDR4 and Optane DIMMs in a two-socket server with a total of 6 TB of addressable memory, “virtually eliminating paging between memory and storage, taking performance truly to a whole new level.”
Intel and Micron are currently producing 128Gb 3D Xpoint chips, this is the same capacity as dense NAND today. We don't know if each chip is actually the same physical size as a 128Gb NAND chip (they are probably larger) but the physical size is not going to be significantly different from current NAND.

So true! I seriously hope to see this architecture realized in the near future.
