Hi Frank, on the privacy aspect of security, there are pros and cons. One of the demos I heard about (I forget which company's product) was 2-player gaming between neighbors on a 1 Mbit link. I didn't personally see it, but was told the 1Mbit link was in no way a limiting factor for responsiveness. I'm sure this depends on "which game" and I don't follow games, but I personally don't think this party line setup is desireable for most people anyway. There are other ways to "intentionally" accomplish the same thing. If this "party line" network is undesireable, as I believe it is for most, it's a (conceptually) simple matter of encrypted bus traffic. Other security issues enter into the picture also, but it's a solvable problem without any extra-ordinary technology. As for the 2 legs of the 220 and how to link them to get complete coverage in a home, here's a link (http://www.intellon.com/library.html) that has one possible solution (article #0050), as well as some other related articles. However, depending on the specifics of the system, several companies make the claim that in their system, the coupling between the 2 legs of dedicated 220 runs (due to the long parallel runs) and the frequencies involved is actually sufficient to make a hard coupling network unnecessary. The question I always had, and I don't know the answer, is whether systems which relied on this "natural" coupling also required such a high power level on the primary feed that they couldn't meet FCC radiated emissions requirements. dh
