CouchDB

[Todd Geist]

Thanks for the responses.


I believe there already is a JSON library in Live Code.  So that isn't the
main issue to me.  The main issue is how to get CouchDB bundled into a
standalone that runs on Desktops and Mobile devices. That is the part that I
have no idea how to do.  I am not even sure if it can be done.  Possiblly
through an external???
