I've been dreaming of a home server revolution for years myself, but sadly due to the fact in Australia the Internet is slow and we're only just now rolling out a national 100mb fibre network which won't be finished for quite a few years and will be expensive with little guarantee of a decent data allowance doesn't give me much hope. Cloud storage is definitely not ready for the prime-time yet, I don't trust it and as Amazon has proven even they haven't even quite worked out how to reliably provide cloud services.
