I've never used one.

From what I understand, they have trouble negotiating different phases. American power is ~120v, two phase, push-pull to get ~240v. So if you plug into a 120v on phase-A, it has trouble getting the standing wave across phase-B. And even more trouble negotiating the circuit breaker box because of all the line noise.

They're limited by attenuation. No one injects more than a watt to keep the signal localized to your house. Poor encryption even if it can be localized to your house. 100KB/s at 6 meters run, 40KB/s at 20 meters run.

You're better off getting a ethernet-converter (or a couple WRT-54GL's using DD-WRT), using WPA2 and a very strong 63-character PSK, putting a cantenna or some other directional antenna on it. Across a house using two cantennas (right receive, left transmit), 4MB/s is very common if the WRT's are put on top of a bookshelf or something. Get a really high power ethernet converter (250-400mW), and you'll get even faster speeds than that.
