Wireshark. After all, libpcap has been ported to all platforms worth mentioning.

I suspect that JungleDisk is primarily to blame here. Most programs (certainly the Windows search indexer) already know to treat files on network drives differently, otherwise they'd be unusable in business environments where you have a variety of SMB shares mounted on every computer.

If JungleDisk appears as a local drive, there's your problem. This is just speculation though, as I can't be bothered to give them my credit card details just to test that theory.

You misunderstood what the problem was. It was not that JungleDisk was downloading backup data, it was that since the AWS 'drive' is mounted as a local drive, when indexing happened (or when the antivirus scanned the files), Windows (or the antivirus) would download all the data they where trying to access. I'd actually go with the antivirus in this case, but it certainly is not JungleDisk's fault.
