Just curious what other people are doing with their Plugs. I have three Dockstars, filling various niches around my home. I won't claim the "biggest dork" award quite yet, but I wanted to share my setup.
1) Dockstar running Arch Linux ARM, in the server room. It's hard to beat these devices for quiet efficient hardworkers. I'm using this machine to run Samba, full disk rsync snapshots, disk encryption (with dmcrypt), and some sshfs/encfs tasks with fuse.
2) Dockstar running Debian Lenny as a wireless motion/webcam sensor. Here, the Dockstar joins my wireless network, and outputs images and movies of my parking spot onto another machines harddrive (via Samba). It's been up for over a week with no problems. I have a crummy 640x480 webcam that uvcvideo likes.
3) Dockstar running Debian Lenny as a lightweight terminal. Hooked up a iMo USB display (ulfdb drivers work like a charm), along with wireless mouse and keyboard. I can run lightweight apps like conky, adesklets, openbox, and xterm, but Firefox is understandably slow. However, as a rdesktop or VNC client, it's perfect. Enterprising individual could use USB over IP to setup a remote docking station to another machine (http://www.virtualinsanity.com/index.php/2008/11/20/a-slick-usb-over-ip-solution-that-i-use-every-day/).
I've played with other setups, too. I had one dockstar acting as a wireless/wired access point using my USB cell modem & dnsmasq. Also, I toyed with a streaming MPD server (for the iPod/iPhone mpod app). On the dockstar, however, the MPD server's lame and ogg encoder were too slow resulting in a jumpy stream.
What else have y'all been up to?
