In the case of the bmx6 renderer the module generates a JSON that gets rendered in the clientside

Just some lua code that is based on bmx6 command line interface.

No documentation... Just code :)
Not that hard
It is in http://GitHub.com/libremesh/lime-packages

Inside packages folder there might be a luci-bmx6 package or similar... Will send you the precise link later
