Thanks for the tip. I have been considering the possibility of small form factor or single board computers (SBCs) for this project, comparing and contrasting the arduino to say...a Soekris or an Acrosser. They are very different beasts.
It is an interesting question, especially considering the fact that an SBC requires a full on OS like FreeBSD, Linux, et al.
