I received my SheevaPlug computer on Friday. Here are some pics of what
I got: http://www.the-ownage.com/?p=830
I have noticed that there are several other companies now using this
exact same model, and basically re-selling them as fancy NAS devices.
Here is some more info on that:

products is near the bottom).

I havn't really gotten a chance to put it through its paces yet, as I
have been slowed down by trying to compile the uvcvideo module so that I
can plug in a usb 2.0 web cam for testing some video-security
applications I am working on.

Since I'm ssh'd into it now, I will just cut and paste some stuff:
