Yes, he is. He doesn't have his own form, holographic or otherwise, but he can pilot my suit, which I'm more than willing to have him do in any situation where anyone would be hesitant to send even protected people. I'd prefer not to have the suit damaged more than I can fix, but the offer and option is there.
He can access a wide variety of systems, but only with permission when it comes to personal communications because we respect people's privacy, so he can feed back any information to this network or someone's phone or communication devices. He's far from all-knowing, especially because his information comes from Earth worlds before Vallo but he's very much a busy body and pain in the ass, so if it's public here, he may know it, have seen it, or can easily find it.
