Quaking, Ki Throw, and Constructed Pugilist

[hotnasty]

I am using a Constructed Pugilist with a +1 Quaking constructed limb. As a standard action, I use the quaking ability to make a trip attempt at enemies in a 20 foot line. I successfully trip an opponent of my size category or smaller 20 feet away.

Considering this situation, would Ki Throw activate? From my interpretation, using the quaking ability with the constructed limb would be classified as an unarmed trip attempt, and thus would activate the Ki Throw if successful. I would assume I'd have to pass this by each individual GM, as one could argue this doesn't make a huge amount of sense and Ki Throw would only work if I could physically reach the opponent. Still wondering if this technically works.

I seem to remember some errata or FAQ about it but for the life of me I can't find it. Reading the Ki Throw feat though, it does mention "target", and with Quaking not being targeted I feel as though it would not work.
