I heard something mentioned about a 'SmartCash privacy oriented sister coin' but try as I may I can't find any info on this other than the brief mention on SmartCash twitter, any more news ?

There is also mention of a new function of being able to send SmartCash to an email address via the web wallet, how will that work, does the recipient need a SmartCash wallet, and will this be available for desktop wallets ?
