Now that Arc runs on mzscheme 4.x, it's really easy to run Arc on a SheevaPlug; it's just the same as any other Linux box.
I had tried running Arc on the SheevaPlug in the mzscheme 372 era, but that was a disaster. Mzscheme 372 isn't available for the ARM processor, so I tried compiling it myself, but the ARM FFI support wasn't there yet, so the compile broke, and I tried to work around that but ended up in a maze of compilation errors. But now you can just install the mzscheme 4.x package and you're set.
I was thinking along the lines of automation lines/robotics or remote location web services running automation..... ie. you could walk up to one of many remote sheevas then hook up a portable mimo monitor to interface with it.
Arc having an interpreter where the program can dynamically be updated should be huge! potentially no downtime to optimize an algorithm running a production line - would save big $$$$.
