I'm a big fan of fermenting right in a corny keg, both primary and secondary. Hooking up a CO2 tank and doing a keg-to-keg transfer makes racking so much easier that with a carboy and siphon.
For primary fermentation I just remove the pressure release valve, stick in some plastic tubing that fits tightly, put the other end in a jar of sanitized water, and it works just fine.
My question is about the secondary fermentation. That's where I get lazy, skip the blow-off hose, and just pull the pressure release valve every day or two. Do I stand a risk of contamination/oxidization if I keep doing that? My last few batches have been Ok, and I figure CO2 is heavier than air so it should blanket the beer, but I was wondering if any one has experience with this. Should I even bother pulling the release valve?
