IIRC, the project, as far as the simulator goes, is over. They got their stats and the site is under archive status at DARPA.
In one sense, that leaves it open since there's not likely to be any further development, but it's also more akin to the sim that DW evolved from, and that's not a retail program, but a government one. While the mods that are available for DW may violate the Sonalysts terms of use to a varying degree, ACTUV is a Sonalysts project for DARPA, and that could be a different ball of wax when it comes to the terms and their enforcement.
