If I wanted to steal coins, I would have been far better off with something along the lines of pirate scam (entraping people with greed is far easier than entrapping them with a feature rich service - much less code that way

)
While I wait for your efforts and others to develop...
I was looking around for a way to dispurse more of the BTC that I wish to trust with a single on-line wallet (blockchian.info) and notice 'strongcoin' and there actions to fuck a thief (which I found both appropriate and highly amusing.)
In researching 'strongcoin' I spotted no significant discussion on this forum, and much more importantly, the actual personally identifiable information on those behind the effort was, in my opinion, sorely lacking. Although it could be bogus, the amount of information along these lines which ~puik saw fit to publish was/is a strong selling point to me in using the blockchain.info solution.
I only mention it in case it influences how you structure your offering as things evolve.
