That would be really cool, but I suspect that compression would 
significantly "fuzz" the ability of that trick.  Now, if you were 
just using PRI channels inbound or G711, maybe there is a chance, but 
someone who knows more about the audio spectrum of microtremors and 
the human voice would be able to answer more definitively.

Let me propose this:  I would love to see a channel driver 
(pre-channel driver?) that allows for modulation of  voice on either 
end of the channel, to allow for voice disguising via a handful of 
parameters that can be changed on a per-call basis.
