I always keep in mind that in traditional culture, traditional 'oli is ONLY to be done by LINEAL authority.  It is maha'oi or ni'ele for non-family to 'oli another family's 'oli.  For example, notably, King Kalakaua composed his 'oli that is presented as a Kumulipo...intended as direct lineage to migrant Pilikaeaea of Tahiti.  Yet, almost everybody today in hula maha'oi that kumulipo as if blood kuleana and 'ohana ku'auhau to King Kalakaua.  I'm amazed that Kalakaua get so many direct descendants today.  Even get immaculate conception kine, 'cause plenty doing kumulipo no more even Hawaiian blood!
