RO only runs best on ARM because it can't run natively on anything else. I would happily see it ported to run natively on other hardware, which in practice means (or at least includes) Intel's x86 line because its cheap, readily available and - importantly - is much faster than any ARM-based hardware.
If RO, or at least the key parts, were open sourced then it could save a lot of time by allowing porting rather than complete reimplementation, or at the very least serve as a reference implementation to answer the "what does RO do in this case?" questions without writing a lot of test code.
With a dwindling market making commercially viable development impossible, and us programmers only able to chip in with what we can do in our spare time, I believe it's our best path forward.
