I just finished reading this article and noticed the above quote as well. At first I thought it was a something I'd read in another article. Then I followed cyncooper's link and low and behold, propertius had posted this some 14 hours earlier:
Just heard from a friend of Alex's that "this thing has a long way to run... it's much nastier than it sounds"...
Propertius, can you shed some light on this? Have you been contacted by Adrian Blomfeld or Andrew Alderson?
