I wrote a small library to forward a TCP socket from a computer to an Nspire via USB (NavNet).
This is a demo program that connects to a CoreTemp Remote Server (see http://www.alcpu.com/CoreTemp/addons.html
Currently it works with Windows and the official TI-Nspire software, TiLP and Linux support might come later.
Anyways, here is a video:
Github repo: https://github.com/compujuckel/nsocket
The library itself is a work in progress and can only forward one TCP socket at the moment.
It could be used for a variety of things like browsers, IRC clients, etc.
Thanks to ExtendeD for giving me the source of his Google demo.
