If someone really wants to go out of his way to cater to plug and play users (I don't), he can run a supernode service for these people to connect to so that they may sweep their funds without the need of downloading the blockchain, and move on to a wallet that is more suited for their needs. I don't have the time to take care of this, nor do I want to deal with the group that's going to just piggy back off of the service and complain when I take it down after a while.
Bitcoin's made me enough money that I'd be delighted to run such a service.
Assuming the supernode is running on an isolated host running only bitcoind plus armorydb, can you think of any security risks from allowing internet connections to armorydb (More specifically, to the http proxy that is used)? Can you offer any kind of guidance as to what the bandwidth usage would be like, both upload and download?
