The Linksys GPL Code Center now has the source code for two versions of the firmware for the WRV200. I don't know when they appeared. The tar files are timestamped this month. (I had made a "demand" of Linksys to provide them a few months ago.) I had trouble downloading the files. It appears as if the FTP sever does not support passive FTP, all that I will allow through my firewall. I have not looked inside the packages to see how feasible it is to hack on the source. The source release need only include code that is GPLed, so key parts may be missing. I also do not know about the build environment. Since Linksys appears to be delivering the new units with 1.0.13, they are obliged to release the source for it. This appears not to have happened.
