Can hand-rub poly be poured (in drops) then spread?
I found the best results with wipe on poly come from lots of thinly applied coats, rather than slathering on a thick (poured) layer, so although you can pour it you probably won't get super smooth results from doing so.

As I understand it, the theory is thin coats of wipe on varnish dry much faster than a regular brush coat.  Much of the roughness in a finish comes from dust/airborne particles that land in the finish as it dries.  Less drying time means less time for those particles to settle, which results in a smoother finish.
