A RPi to complement the HE is what I suggested some time ago:
I "baptized" it as a "companion" because it would be a real companion to the HE platform, implementing complementary functions, as the ES local cookie refresher server, local WebCore, backup handler and so on - the possibilities would be endless.
It would consist of a Docker environment where someone could add HE-specific pre-configured images (like the ES and WebCore) and configure them, directly from the HE - no need to know anything from Linux.
So far, it's a dream - but dreams someday come true!
