Why?
I manage to get a few of these and after some annoying searches on google I noticed there is not so much known about these little ethernet/serial/webservers.

This made me happy. until I noticed all the cool stuff was hidden behind NDA's and the SDK. Lucky for me the manual and a japanese guy got me started on programming them with perl. See XPort GPIO from Perl.
