If I'd had lots more money ($249 instead of $99) and been about a month later - before the current back order situation - I'd possibly have been tempted by an OpenRD board. [Think Sheevaplug in metal box, with audio, video, SATA disk connections also brought out]. As it is, I didn't get the chance.
Instead, and to help demonstrate the capabilities of the little box, I added some packages - it now has X Windows, KDE and Apache installed.
I opened up SSH to allow a friend to pick up the files needed to install up to date U-boot, the Debian base system from Martin Michlmayr and the "I bricked my Sheevaplug" alpha installer. He, in turn, took great delight in running various X applications on the Sheevaplug and has promised me screen captures :)
From Sheevaplug -> Atom machine -> cable modem with port forwarding -> cable modem with port forwarding -> firewall -> firewall -> his machine and STILL acceptable performance :)
