Thanks xeroc for your reply. I'm certain you have more info about the stealth functionality, especially the GUI elements that I've never seen. I do recall providing @dantheman with feedback on his intended GUI design but I don't recall him offering much if any dialog about it. Some of that I believe can be found either on the bitsharestalk forum or in github issues.
Also, I was under the impression the primary reason dan didn't move ahead any further with stealth was he couldn't or didn't find a method to protect/backup the password he found acceptable. Not sure if his subsequent work on password recovery in steem is applicable to the (same / similar) problem in stealth or not.
BTW, is the jcalfe GUI work available as MIT open source on github?
Thanks again for all you do for this ecosystem. If it weren't for you I am certain BitShares would not be the great product it is!
One last thought - are you aware of any discussions past or present concerning a proper and thorough code audit of graphene? Is that even possible (i.e. are adequate specs available for an independent 3rd party audit service to perform such an audit)?
