O2 level/ppm for recipe and tools

Just a thought, it might be noteworthy to have a O2 ppm as part of the recipe.  For those folks who do oxygenate with O2; or perhaps an air-pump.  Ok, I know it's overkill...

Another area though, the tools section could have an O2 calculator.  Like:  How many ppm of O2 are you trying to obtain (8-12 ales; 10-15 lagers)?  Flow rate?  Time?  Pure O2?  Aquarium Pump?

Thanks!
  I had not heard this suggestion before but it is a good idea.

Cheers,
