Sounds good any chance of posting up some pics. I have a linksys myself that I use as a client bridge to serve my pi, and have been thinking about this myself especially as i have just ordered my second pi.
On a side note I have been powering my linksys, wrt 54GS, from usb so,ckets for a cople of years without problems. I have powered it from my printer, my laptop, my telly, eeepc, xbox 360, apple usb charger and it has never failed. All I did was cut the cable and attach a usb cable an of course if you wanted you could always add a female usb to the original transformer if you wanted to have the option to use it.
