Did a python implementation of this at https://github.com/monty888/txbroadcastr.

Thinking about how events could be wrapped, decrypted and relayed so even without TOR it wouldn't be easy to know who posted the original event. Also thinking about adding some steganography to the mix...

And if nothing else it finally force me to write some code to monitor a directory and post any TX to the bitcoin network so I don't have to mess around manually opening a wallet to post signed txs from offline signer.
