I'm not sure how real the risk is of contamination when one does aeration, but I was thinking about doing something like this:
A container filled with sanitizer, with an in/out ports for the airhoses.  the intake tube goes into the sanitizer, so the air needs to bubble through it before it hits the airstone/wort.  Has anyone done something like this?  I imagine it would work pretty good, at least better than using just plain air. 
What do you guys think?
