The Dropbox client is running with normal user privileges on a computer that you have root access to. It should be possible to use reverse engineering/debugging tools to either bypass SSL checks or analyze the dropbox client binary to see what is being sent/recvd.

Sure, I'm just saying it would be less straightforward than mitmproxy. I wonder if there are tools to hook into whatever SSL library is being used (OpenSSL?) and intercept traffic before it gets encrypted and after it gets decrypted? (probably using LD_PRELOAD, like tsocks)
