Recently, Open Door Networks published a widely-reported security alert concerning Apple's implementation of WebDAV access to the iDisk in 10.1. The essence of the security hole is that your password is sent in cleartext, where it could be interecepted by anyone sniffing the network.
While I agree this is a fairly major security issue, I had other problems with iDisk in 10.1 -- speed, or the lack thereof. It seemed that, at least on my connection, webDAV access crawled. The disk would mount quickly, but copying even a modest 400K file could take minutes at times. This used to take five or ten seconds.
It turns out that the solution is posted on the advisory page at Open Door Networks. Simply use Appleshare to connect instead of WebDAV. Under the Go Finder menu, select "Connect to Server" and enter afp://idisk.mac.com. You'll get a username and password box, after which you can mount your iDisk like any other Appleshare volume.
This isn't a perfect solution -- it takes me longer to connect via Appleshare (the Finder gets the spinning rainbow disk until the connection is made), and the 15-minute time restriction comes into play again. However, it's worth it in exchage for greater security and the speed increase I get when actually transferring files.
