I've been thinking about this for a while now. Elite Dangerous is a really nice graphical front end on top of the background simulation. The specs required to run the game are reasonable by today's standards but there's no good reason that they couldn't be much, much lighter.
Elite, in 1984, was a 3D wireframe game running on a procedurally generated galaxy and it ran on a tiny fraction of the resources we have available today. I'm seeing no good reason that it couldn't still do that.
Raspberry Pi's are complete computers and they are magnitudes more powerful than what we had back in 1984. David Braben, current CEO of Frontier Developments and co-developer of Elite is also a co-founder of and works as a trustee for the Raspberry Pi Foundation.
My question is this; When will we see a low spec'd UI for Elite Dangerous that runs on a Raspberry Pi?
I'd sign up a few extra accounts to play with that. :)
