Yes last I checked you could still build firefox on platforms they didn't have a JIT for, so it certainly must be possible. Sadly, SpiderMoney isn't as commonly used for embedding compared to V8. Maybe Spidernode will take off in the node community and make it a more popular option... we'll see.

From watching the video it seems that Ignition is ~2x slower than JIT which sounds like great performance for a non-JIT'ed implementation.
