Actually, of course, it precedes karate since Okinawa at the time was not yet part of Japan. "Okinawa" te is a general inclusive term for localized schools such as "Naha" te, etc.
There are some very pretty (artful) uses of that te's concepts that can be used with aikido as they are circular. Additionally, I like the idea of a defense that can embody an offensive response at the same time. I understand it's not quite orthodox aikido, but perhaps in a multiple attack situation it could be considered "atemi with ki."
P.S. My sensei of 10 years is from Guam originally and has a number of uncles, and a grandfather who were taught by various Japanese and Okinawan teachers, as well as Guamanian.
