Well, the boards came in, and I built one (except for the 1M resistor). I then clipped a couple different values in, and Stan was right, there is significant timing variability, the timing with a 1M resistor was only around 800ms. I have different values coming from 820K to 1.2M, good thing resistors are dirt cheap. 
It looks like it should fit into the DCS-RC easily, I did take the three pin support strap off to give it a lower profile, total of about 3/8" above the DCS-RC PCB.
FWIW, I got 30 PCB blanks, and I have components to make 30 units. I have 20 already committed, so there are 10 more that I can deliver. I have 8 more for people that wanted one, so they get first crack, that leaves two of them still "free". Act fast, because I might decide to keep one.
For people already lined up for these, they should ship out next week, I figure I can whack them together when I get back from York, the resistors to tune them will be here by then.
