Stilton from Stilton?

There was a good piece on the radio this afternoon about food myths, and a wedge on why Stilton is called Stilton when supposedly it was never made in that particular village, instead just traded there. The cheese expert (Richard Landy) has found evidence that cheese was manufactured in Stilton from Roman times!

So currently a Stilton can only be made in Leicestershire, Derbyshire or Nottinghamshire...... but not Cambridgeshire, where the village of Stilton resides. So will the Stilton trademark come under threat from the Stilton village cheese-makers?
