There have been occasional false security alarms about iDisk, dotmac and me.com. My favorite was ‘OMG, huge security hole in me.com services; If they know the URL, anyone can see your iDisk Public Folder!’ Obviously this was NOT a security issue. OTOH there have also been legitimate reports of flaws in the system, which apple has fixed in a timely manner.
But always lacking was a definitive statement about what is, or is not, encrypted on the wire. I’m here to report that your iDisk data travels the internet encrypted. Using Wireshark I was able to assure myself that updates to your stored iDisk files travel encrypted.
