I did some casual reading on WP about geons. I understand that they have only been studied classically, and in a classical theory of course their angular momentum wouldn't even be quantized. But they were apparently intended as a candidate for the ultimate building blocks of nature. In that case, I don't understand where the half-integer-spin particles would come from, since you can't generate half-integer angular momentum from orbital motion. Anyone know anything about this?

Apparently it is possible to get fermions from bosons: http://arxiv.org/abs/cond-mat/0407140.
