Looking at Lostpedia, I see not much of info has been made available on the Temple thus far in the show (thought I might be missing/ forgetting something but no..) So with reference to the name only, I'm assuming it's a communications-related station, but not necessarily in the sense of some station with com. gadgets. A temple is where believers gather to reflect and hope in the light of their faith, so it always has some transcendental quality with reference to some higher power. Probably a far stretch but could the temple be some place where departure from the island could be arranged somehow..? Or a significantly safer place for islanders in the sense of being a place with exceptional qualities, protection etc...? I'm aware that's somewhat obvious, but I wonder what exact qualities a place as such might have..?
