Thx for the help JoelKatz!
It sadly isn't on bitcoincharts.com though

I forgot to mention that I was checking that for several hours after making the transaction, and that it never appeared there...
I wonder, is it possible for me to "undo" this transaction since it's been so long (days) without the network taking notice of it? For all intents and purposes, it seems as though the transaction simply doesn't exist except in my local bitcoin client...
