Pd or otherwise, I'd be very careful about sending any messages back and forth with the actual Bitcoin network.  By doing so you are essentially telling the internet that fungible, irreversible tokens might exist on your machine, the value of which could far exceed anything that you have ever or will ever store on your computer.

Also, blockchain.info likes to store the IP of the first node that told it about a transaction.  It's pretty well connected, so if you make a transaction from your machine your IP is very likely associated forever with that transaction.  (Just one of many ways in which Bitcoin is not anonymous.)

But of course if you happen to be in Sochi then everything of value on your machine has already been stolen, so knock yourself out. :)
