it woudl be great if you could publish a proper data sheet / user manual that contains a description of *all* connectors/buttons. This should be a real PDF document and not just some records in a wiki / on a web site, preferrably. So far, some of the information is on www.jaguarboard.org:8090/display/ED/Jagu...f+External+Interface
(like the GPIO/I2C headers), but then other parts are found only in www.jaguarboard.org:8090/display/ED/Jagu...+Installastion+Guide
But then, very important information like which GPI the individual buttons are attached to, is not available at all, it seems. It just states something about what a windows driver does, but that's not hardware documentation.
You might even go one step further and think about releasing the schematics of the board. Other established suppliers of small-form-factor x86 boards like pcengines.ch are doing this for more than a decade. It helps a lot when doing hardware system integration or driver development on the board, and would allow users also to find answers themselves (like which GPI is this button wired to).
