Rather, a chip on the PC´s mobo which route the PCI signal through Ethernet.

Save the cost of the PCI connectors. Well, for the purpose of a flat panel with a g-card, I´ve trangressed my own rule to not bother with the assembly possibilities/limitation firstly. I realise that I was focusing on PCI slot just because the g-card could be removable from the monitor, hence upgradable.

I stand on the monitor side, Nick, and by "mainboard" I don´t see exactly on what side you stand (maybe the both) Beside the cost, unless a 90° PCI slot exist, one can use a raiser card too. > > > > > > Does that require a "special" chip between the PCI slot and the Ethernet > > > connector ? snip > > If you want a single chip it would probably have to be special.

Certainly the things are a little bit confused in my mind, but this kind of implementation is what I was speaking above. > snip > > By "more than a modem/router", do you mean "have multiple Ethernet > > ports", or something else? no, something else, below > Certainly, if you have a DSL modem with > > some variety of hub/switch/router built-in, you could plug the > > screen into the DSL hub rather than into the computer.

I suppose that that differs from a country to an other, but there´s 5 years ago, French ISP let the consumer choose his DSL modem/router. Nowadays one doesn´t have the choice anymore, you take the ISP´s box with the triple play (Voip, TV, Internet) and optionally suscribe to a security service (AV, FW, anti-spam, and so on). All that let me suppose that such ISP box is more than a modem/router. > > This brings up the issue of security - constantly sending your entire > screen over an insecure network is not a good idea. The really frightening thing is a compromised Cisco box, projects this idea on every ISP box which seem to be more than dumb modem/router...

So the electronic is there, the displaying device differs (Projector´s lamp, CRT tube, LCD matrix, though each has their own implications) Hence, the idea of a monitor with graphical ressource inside is nearby to arise. Wouldn´t be strategic for OGP/C to provide a balanced chip + an as low power cpu as possible combination ? And why not, an fpga implementing video signal through Ethernet, which seems to be the best path available ? > > nick > > _______________________________________________ > Open-graphics mailing list > [email protected] > http://lists.duskglow.com/mailman/listinfo/open-graphics > List service provided by Duskglow Consulting, LLC (www.duskglow.com)
