Looks like folks here have already answered the question on oxygen that was posed. It does filter contaminants but does not remove oxygen. With that said I see a breathable seal as an issue for long term storage, once the pressure is mostly stabilized then a liquid airlock would keep everything out, including air, where this may remove the bugs it would allow air to creep in.

I just used this to cold crash a beer, I figure having a bit of air sucked back is better than dirty Starsan. I'm getting ready to secondary a saison on some peaches and I'm going to try it out there as well. I still like the idea of this for primary/secondary fermentation.
 
Any updates?

Left my saison on peaches for 3 weeks and it's carbing now. Samples were tasty and showed no signs at all of any off flavors. I'm brewing again this weekend and I'll use it on a full brow, after the initial vigorous fermentation with a blow off, and see how that goes but from initial testing it seems good.

I'll post another mini-update when the peach saison is done.
