i did a 12 gallon batch in a keggle. We did a 90 minute boil, and after 45 minutes of the boil, we added the rest of the runnings. There was risk of getting DMS from not doing a full length boil on the entire volume, but the beer came out great.
I'd rather have a bottle in front of me, than a frontal lobotomy.
You can't be a real country unless you have a beer and an airline - it helps if you have some kind of a football team, or some nuclear weapons, but at the very least you need a beer.
