Found this http://wmltd.co.uk/index.php/products/sumo_thin_client and it seems that they built a gtk interface for nx client stuff (look screenshots). They call their distro Foundry Linux, I didn't understand from their website if it is GPL (probably yes), but if it is it should be possible with less effort to build a full featured (full screen capable ) nx client for the 770. Gonna look more into this.

Bye, tira.
