AFAIK, Linksys WRT boxes are Broadcom reference design. Versions of Linux with approriate software to run on the box has also been created - OpenWRT, Sveasoft etc. Why not create a LEAF implementation (MIPS based) on the Linksys boxes? This way we will get cheap hardware $50-60 instead of $150-250 for PC compatible boxes.
Do you have any specific information on availability and pricing of a "devel-kit" for those things? I mean, it seems somewhat unlikely to me that the boxes themselves have everything one needs to deploy a new OS on them. Time permitting, I'd be willing to play with it, but I really wouldn't want to have to reverse engineer half of the box just to find out how to copy the OS onto such a box. Finding the right drivers and getting them to work might be hard enough
anyway...
I believe the Linksys firmware source kit is all you need. It is Open Source, not available for all Linksys systems but for most current ones. I know the sveasoft firmware is close eough to a standard linux to support the firewall builder scripts. I guess shorewall would be fairly easy to port. The current kernel is according to the makefile a 2.4.20, the Busybox version is 0.60.0 according to the Changelog. It uses uClibc so I guess changing/adding functionality should not be that hard. The code for the broadcom wireless stuff is object-only though.
Some source code leaves doubt on its adherence to the OpenSource license.
