Thank you, Rickard! I loved that article!
Just one more thing -- I checked my Rocci dictionary of Ancient Greek to Italian from my high school years. Anyway, "daiphòbos" (adj) means "the one who frightens (his foes)" -- "dai-" (the Doric form for "dei") comes from the adjective "deios" ("hostile" > as a noun "oi deioi" = the enemies), whereas "phobos" comes from "phobéo" (which means "to frighten").
Sorry for coming up with this so late.
