>Has anybody on the list created a "secret language" such as this?  I
suppose this might be counter-productive to a list like this (where the
entire purpose is sharing your work,) but I wouldn't be surprised if the
practice is relatively widespread ...

Sai's and my gripping language (another phonology post upcoming soon) has
secrecy as one of its design goals, but the secrecy is meant to be an aspect
of the medium, steganographic-style: if others present don't know to pay
attention to the speakers' clasped hands the hope is that they'll not
realise anything is going on.  

Whether we should make the description itself secret is still being
discussed.  We see no harm in describing the phonology here, for instance;
and I would even be willing to publish the lexicon, but Sai might not want
to do that?
