The netgear WNDR 3700 is running a version of OpenWRT out of the box with a custom interface. OpenWRT has a few builds of their standard distribution which work, with full support being rapidly added. DD-WRT is working hard on adding support for the router as well with at least two test builds being released. Full support should be there within a few months. Again, with it running a customized OpenWRT out of the box, it is only a matter of time for all the router based distributions to have ports which run on it.
