As a postscript, Cedric (of the Bedlam Bards) said to me this morning:
"Hooray! Something to give for Christmas to those who already have Firefly and Serenity!
BTW, if you're thinking Christmas will be gone too soon to give this gift, just remember that historically, the Twelve Days *start* with Christmas Eve, and the Yuletide is not really over until Twelfth Night/Three Kings Day, which is in early January. So late presents aren't really late; they're just historically accurate!"
