Hmmm...sounds like this would be of use for, say, a front-end transistor where you could dedicate a heatsink to that one transistor and simply bypass insulators and all concerns about the heatsink going live.
The 'conductive under pressure' part worries me for any other application, though. I am assuming (perhaps incorrectly, granted) that if this stuff is conductive under pressure that it will also be conductive when <i>not</i> under pressure, although presumably to a lesser extent. Supposing that you were to use it with a mica insulator and some slopped over the edge to contact the heatsink directly. Would this lead to a high-resistance (hundreds of k to perhaps M ohm range) connection? I can see where you might have to be scrupulous about applying the compound; not allowing any to come into contact with the heatsink. High PIA factor if that's the case.

Arctic Silver is made of micronised silver suspended in an electrically non-conductive paste. So it is capacitive under low pressure and electrically conductive under high pressure .... of course if the voltage is high enough it can be slightly conductive under low pressure also.
