Oh, and there is talk about changing the trust regulations so that all principles of the trust must get finger printed and go through the standard LEO sign-off. The comment period on the BATFE regulations is currently open, and if I recall, closing in early December. If changed, I don't know when it would take effect, but I wouldn't wait.
