Just found this thread, fascinating, I suspect that the results we saw on the BBC programme were accurate given the variables, and some have shown promising results on this thread after testing the theory, but some have spiked more than a desirable result.
I will give this a try soon with wholegrain pasta and post the results, it looks like from where I'm standing that just like starchy carbs some will tolerate it and some wont, but either way I think it's ultimately going to pave the way for more research, we may end up with a product that will put pasta back on the dietary list for diabetics.
Here's hoping.
