No guarantees, no. But my experience with carrier-current stuff is you're lucky if it has enough range to work everywhere in *one* building. And this isn't WiFi; a bigger antenna isn't going to help. ;) So in that case you're into a scenario of someone with an oscilloscope noticing the signal and building something custom to amplify and demodulate it. Technically possible, but unlikely unless your network is a really tempting target for some reason.
At any rate, the easy solution is to run OpenVPN on top.
