why on god's earth would subsecond anything matter in a nonmilitary situation?

are you willing to pay a cell tax AND a protocol complexity tax AND a device
complexity tax to make this happen?  do you know what that will do do your
TCO and therefore your ROI?  you want to pay this tax 100% of the time even
though your error states will account for less than 0.001% of the time?  you
want to have the complexity as your most likely source of (false positive)
error?

if so, then, you misunderstand.
