Penny/Scott,
You've got to realize that no "closed-loop" device will be delivered to us with the current CGMS technology - you're both right that it is not accurate enough. But these R&D projects are probably going forward with what is available today knowing that CGMS accuracy is going to improve to the point that it can be used for dosing.
They would be stupid to sit back and wait for CGMS to get all the way there before attempting to develop the software (the "algorithm" as this article calls it) and integration with a real delivery technology (OmniPod, in this case). Waiting would be foolish, so they're getting a head start now and will integrate new CGMS tech when it becomes available.
Put another way: the efforts do NOT have to be done in a serial fashion (where one step has to finish completely before the next can begin), they can work in parallel. That is the smart thing to do.

Count me in that skeptical category. Although it is good to see it being worked on.

I wonder how the slow absorption of insulin and accuracy of CGM (and good old fashioned BG meters!) will be overcome?

To say I'm skeptical would be an understatement. What's to keep the thing from going haywire? I don't even trust a GCMS, why would I trust one attached to a pump? I think CGMS are great but you're not supposed to dose by them. So, how do you do that in a closed loop system?
