You need a lot of little shiny objects in this line of business.

I think you've been staring at too many "little shiny objects".

I think the practical application would be backup. Some media which

would be fast enough and cheap enough to take regular backups.

I can buy a TB of IDE disk for ~$1k, but I can't buy a practical backup
system any cheaper than another two (or more) sets of drives, in some
way removable. To balance the cost of backup to the cost of main storage
I would guess reusable media would need to be ~$100/TB, use once no more
than $25-35/TB so you can sell it into the home/SB environments.

OIC, so it's not so much as a replacement for RAM or Flash, but more as
a replacement for CD/DVDs, etc.?

The designs I saw could be considered that, as long as you are talking about
the RW varieties of those devices. They used crystals of something like
Lithium Niobate to record the data. They also had some "odd" access
characteristics. When you flashed the laser to read a block of data, you
got a huge chunk (~100 MB) at a time, with extradinary transfer rate, but it
put so much energy into the system that it had to cool down for several
seconds before being accessed again. Of course, this was just one proposed
device and AFAIK, it never made it past the prototype stage.

Never underestimate the bandwidth of an Escalade full of holographic

I thought I made my opinion rather clear; I'll care even less by
the time either technology is useful.
