Duplexing the method used on the Braille cipher would seem straightforward enough at first glance... but why is nothing working?
The original method was shifting the alphabet by one step after each character including spaces and punctuation but eliminating spaces when possessive form was used, or something like that. One of the definitions for "duplex" is "twofold," so perhaps we needed to shift by two steps after each character... but nothing coherent is coming out of this method.
Another idea was to run the entire thing through twice - so shift the whole message one step at a time and then take the resulting code and run it through again. But once more nothing resembling words has appeared.
Some other cryptonauts suggested another definition of "duplex" which is used in telecommunications, where a signal flows in both directions at the same time. We tried a mixture of two alphabet shifts, one starting from a and one from z and mixed together like so:

No luck.
We've considered that the coded message may be backwards as well, and ran the same tests on it both ways. Still nothing! I'm going to bed [:'(]
