I don't know about growing them from seed, but below is an interesting link about growing them from seed. Unfortunately, you probably won't get what you think you're getting. T&M knows that, but don't say so.

Here is a link that might be useful: Olives from seed

Bonsai folks grow olive from seed, but they don't want them for fruits. But you can read up on some bonsai sites (or go over to the bonsai forum on GW) and see what you learn.
From wiki: "The olive is also sometimes raised from seed, the oily pericarp being first softened by slight rotting, or soaking in hot water or in an alkaline solution, to facilitate germination."
