It's multipurpose, so she can use it at close-range for Dustly-goodness, but I wanted to know about remote Dust usage in the circumstances I outlined above. Ah, now I see.

Based on what we've seen, the Dust needs to be very close-by. As far as I recall, only Blake and Weiss have been shown combining Dust with their Semblances.

And on both cases, said Dust was in their weapon. For Blake, it was in in her magazine, and for Weiss it's always in that revolver cylinder. And on Weiss's case, it didn't matter where she placed the Glyphs.

So, not literally "must be touching it", but at most some centimeters away, and what matters is that the user has Dust nearby.
