Passing along a comment a friend made:

I'd be interested to see what he's done...  If somebody goes along,
convince him to put some info up somewhere about it.

There's plenty of ppl who datalog their roast temps vs time so that they
can repeat a roast exactly (or almost exactly).  I imagine he's PIDing
the roast profile to get it to where he wants.

Even the pricey home roasters (Hottop for instance, ~$1700
http://www.dibartoli.com.au/product_details.asp?pid=340) are still
pretty clunky in their temp control.  Having something that is more
infinitely configurable would be a good thing (and rather sellable, I
would have thought).
