Thanks! I've been working 24/7 running a 6-week summer program, after which I finally get a real bona-fide 6 week break. Thus a reasonable time frame for finishing PSB is the end of August (and I'm actually quite confident about that).
Unfortunately, it appears that my thumb drive with ROTP got lost in the mail to England (on its way to Adywan for color correction). Meaning that I'll have to buy another one and start that process again. Minor annoyance.
