It may have been me, I have asked about similar features before, though
I think on -users. My app does not require exact timing though it does
use the approximate length of a DTMF tone to adjust pump speeds (2 = 
faster, 8 = slower).
Makes site visit engineers jobs easier and gives a paper trail of who 
did what when.
