I think network pentesting has been a topic of mouth for a while now. There was always RTB, but who even knows anymore.. Even if there was some sort of plan for network hacking, we'd be in need of someone who could commit solid time to deving on it. There's plenty of people who who love to jump on something like that, including me, but just can't put out enough time. As for the phone phreaking missions, our top devs on Asterix, what we use to handle all that shiz, up and dipped. So with that it plays into the whole lack of devs thing. If you want, I'd encourage you, and everyone, to submit your own missions. Right now, that'd probably be really beneficial.
