Honey Pot
If I were a hacker I'd be salivating over the prospect of hijacking a telex proxy.
I'm sure that it is NOT the case that this research is so narrow as to say that its job is finished when the telex principle is adequately demonstrated... leaving all other aspects like security as an exercise to the reader. Academic research is much more thorough than that...
In fact, hacking this may make simple work of identifying its users... which would put China at the front of the hacker queue.
