Wuala are selling 1GB of storage for a year for 0.1BTC. Looking on Mt. Gox, I can today (12 Oct 2011) buy 1BTC for about 2.60 GBP. That would be a staggering 26 pence per GB per year. I figure I'll push the boat out and try to get 100GB. I've sent a bank transfer of 3GBP to Mt. Gox. As soon as it clears I'll have a go at buying storage with bitcoins.
