Huh, I have never seen one, but have read about them being used in Australia.
I would use it as a coffee table. Just put a sheet of glass over it! Bam, isn't coffee table.
On a side note, my buddies just got a rubberized keg, I was trying to figure out if it was fully rubber or just coated, but it looked like more than a coating. Maybe just a inner ss lining?
