Many people on HBT seem to be using this pressure release valve:

Do you guys know a Canadian store that would ship this product (or something similar).
To me, seems like a pricey way to ferment beer and takes one finished beer vessel out of the rotation. Also, headspace will be an issue?
1- It has been done many times by people on HBT. Headspace can be a problem, but most people seem to be able to fit 5g in a corny by using fermcaps. The first 2-3 days, I would remove the gas post and be using a blowoff tube instead of the spunding valve.
2- Let you carb the beer naturally (without adding more sugar). I only have a small CO2 tank and I don't want to refill it too often.
3- Once you close the corny, the beer never sees oxygen again (unless you want to dry hop!)
4- A lot of people are saying that fermenting under slight pressure can help reducing ester production, leading to even cleaner lagers
5- Makes yeast harvesting so much easier... Plug a picnic tap and it's done.
6- Cornys are slightly easier to clean than carboys
7- Cornys have a smaller footprint in a fermentation chamber so you can fit more at the same time. Same thing if you want to cold crash.
8- I have 6 cornys and only 1 tap at the moment! So using cornys as fermenter is not a big deal for me.
9- I'm a scientist and I like to try new experiments!
Fermenting: Lion & Lamb IIPA (WLP051), Strongbad Bitter (US-05)
On tap: Cardinal Sin India Red Ale, Count Chocula Chocolate Milk Stout, Lion & Lamb IIPA (WLP001), Strongbad Bitter (S-04)
Basically, when the keg is ready, you simply pour until the beer runs clear and transfer into a serving keg.

The only thing I don't like about this idea is getting the filter off for cleaning. I guess if you cut the dip tube enough it may not be to bad.
I wonder how much it'll improve the finished product. Keep us posted.
Might be a pain to clean but a I'm sure you could set up a half decent Clean in Place system for them.
It would be pretty simple to push the carbonated beer into 2 cornies for serving.
Anyhow, I was pondering on what would happen if you made a coupling tube for a Corny with a gas-in ball lock on each end and a pop bottle adapter on just one end. Then you could add enough priming sugar to a partially full 2L pop bottle attached to the adapter to carbonate the main keg and the disposable pop bottle "primer" brew? I'd guess at ~150g of dextrose @ 68 deg F for a 2.5 gal keg? Would this not be a cheap C02 charge good enough to force carbonate the keg while it matures without the sediment of bottle priming?
Keg 1: Dunkelweizen Ale
Keg 2: Brown Ale (with Safale S-05 & far too much Perle!)
Primary: Brown Ale (with Safale S-04 & Spalt Select this time)
2ndary: Gotlandsdricka (White Labs European Ale yeast)
Dunkelweisen Lager, Pilsner Lager, Nut Brown Lager (all Saflager w34-70)
bottled: Pilsner Ale, Munton's Brown Ale & etc.
