Re: I taint rich! (Fun with raw transactions and disrupting 'taint' analysis)
One that auto-swaps coins with strangers in IRC using this very same flow you've got going here.
I've actually done this manually a few times with a few different people well, IRC messages are too short for most transactions. 
but encrypted pastebins work. I thought it would be fun to get more people involved.I am thinking of this as a program that runs all day and night and promiscuously finds random swapping partners, repeatedly swapping coins as soon as they meet a minimum threshold for confirmations. I suppose if such an application wants a dependency on a pastebin site that doesn't mind being polluted with transient traffic and doesn't require a captcha, it would work.
Such traffic could be broken into multiple IRC messages to avoid need for pastebin. It could also do direct client to client communications.
