In which languages did voiceless plosives become voiceless fricatives?  Is the second "voiceless" an error for "voiced" there?

I'd be tempted to the dialecticism solution, though I remember you've said you want to concentrate your efforts on standard Britainese.  (Does the standard remain the variety of the London area throughout, by the way, or does this change?)

One of the features you've stated you expect(?) Britainese to have is retention of [D].  If one of the features of the second lenition area is the loss of [D], even from Latin *t, then which [D] is it that would be retained?
