To answer the original question posed on this thread by Duff Man:
Does an ATC cancellation of 250KTS below 10,000FT apply to operations in Class E airspace?
No, it doesn't - that speed restriction still applies. Depending on the STAR and where you are, this is usually not a problem, as the high speed descents normally result in steeper profiles anyway. We have been finding jets given high speed are usually at or above F140 when transitioning from E to C, hence they don't have to worry about it.
But it certainly is a consideration and one that is a pilot's responsibility - if you are still concerned, you could ask ATC to level you off At F110 until reaching C airspace or else knock back the high speed, although that might mean you lose your spot in the sequence
