Now that could well be.  I've been doing a lot of messing with these  
boxes, and would be happy to give fellow luggers the nickle tour.   
The OpenWRT environment, in particular, is a lot like working on a  
standard box (it feels to me like I'm running Slackware -- a package  
system so simple and reliable that a cave-man would be right at home,  
an easy arrangement on, er, "disk", and if you do something that  
requires a lot of CPU, you suddenly remember *exactly* why you used  
to be so careful about running heavy programs when you were actually  
running Unix on an actual 386.)

It's *perfect* for tinkering, and the door is open to doing bigger  
things on it (like the management infrastructure that I'm fussing  
with, where all my configs live on central servers, auto-download on  
boot/polling interval/push, etc.)

The main issue is getting 5-10 minutes off from my life so that I can  
prepare such a discussion.  Lets keep it in mind as a maybe for April  
or May?
