Anonymity loss will hamper our being included in Tor browser, which

There is no way for wallets to know their own balance if they share
active coins, so syncing wallets necessarily harms usability.  Anonymity
costs would prove catastrophic too.   

Also, any networked backup system we design requires moving initial key
material, so only power users benefit anyways.  We should operate as
well as possible when user backups kick in of course, ala Apple's Time
Machine.  We can trivially detect restored wallets though with my
suggestion to only back up withdrawals to the reserve.
