A number of issues:
Any issue which will cause this to not work is a serious vulnerability, as someone could have an attacker actively breaking into the device, and this would offer no real protection. Someone intending to use this and finding it not work in the last minute has very dangerous consequences.
May be fixed with end-to-end encryption, but don't roll your own crypto.
I noticed that there is no mention of authentication anywhere in this. What steps have you or are you going to take to prevent this from being triggered by someone not of your own?
An attacker who can MITM the connection can obtain password hashes that they can crack offline, or replay the traffic for undesirable consequences (separate issue).
Might be possible to use this:
https://pypi.python.org/pypi/Dtls/0.1.0
Some sort of real authentication with secrecy and integrity checking would be better.
Tried with default python (2.7.5) , fails to find tkinter (locgical since Tkinter uppercase was before 3.x)
Tried with brew installed python 3.4.1 , just getting "WARNING: FAILED TO BIND TO UDP SOCKET." and nothing else
Tried with official installer installed python 3.4.1 , same warning and nothing happens
Am I missing something ?
