Nobody is keeping track of you for clearance purposes. You report to no one.
So, write what you want and publish it. No problem. As I said before, as a Reservist with all sorts of TS accesses, I never had to seek clearance for anything I wrote when not on active duty.

We really shouldn't make to much of the hypothetical possibilities since the reality is that once the horse is out of the barn...

(Reminds me of the stallion living about a mile away who came to visit my mare - after escaping - while she was in heat about a month ago...)
