Don't confuse my use of "network terminal" with classic serial terminals. Look, for example, at the devices AXEL builds, or already present for many years: Sun Ray terminals. They also have audio I/O, card reader, and USB connectors (where the keyboard and mouse usually are connected). A regular monitor (maybe with speakers) makes it a full-featured workstation. But no data users can mess around with, and its power requirements are really low. Our university's library had many of them, and I liked them because they were completely silent (in difference to the boring beige PC boxes they scattered around the library). You can find specs of an AXEL terminal as exemple here: http://www.axel.com/usa2/prod_ax3.html?mv2_pos=1 They're calling it "thin client", but it's terminal. A box where you plug in a screen and a keyboard and connect it to a network IS a terminal. :-) > i'm > sure my wasted cycles could be put to very good use.

Which is no problem using network terminals, everything you need is a LAN (or maybe even WLAN) connection. Still, multiple GPUs is possible, but results in a major raise of power consumption (because you have to use a "modern" GPU). Multiple input devices is no problem via USB. > the ARM/A-9 chip looks great. its a RISC chip that is super > efficient. gang four A9's in one package:: low power and at > least 2GHZ .... the only drawback is that the a9 is only > 32bits. So we cannot try to calcale the 7th root of > infinity, :-) ARM is an efficient platform in terms of energy, and I think it will be more and more important in the future, especially if you consider the mobile devices market. And when it's good at running on battery, it's good on running on AC power. When the industry comes up with "extra new energy efficient PC hardware", we already know that it existed for years. :-) > i mean, come-on-people, get real. 4G of ram > ought to be Plenty!!

By using means of blocking for known script-kiddie sources, you can get rid of a lot of useless traffic - and possible trouble. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
