MacWireless Powerline
MacWireless on Thursday unveiled a new international version of its 200Mbps Powerline Network Adapter, which allows users to channel network activity through power sockets in their home or office. The technology provides users with flexible network deployment options without the need to run Ethernet cable or worry about poor reception over WiFi due to concrete or other wireless interference. MacWireless is selling each adapter for $100 from its website.
Users can operate up to 16 adapters on one network, allowing for medium sized deployment of network signals.

Of course
If you read the networking threads you'll see that this technology is not all it's talked up to be: want to use a power strip or surge protecter? Nope. Network speed? Assume around 1 MB/Sec as being good. As the wired network is essentially shared, every new connection drags things down.
In terms of security? Probably not much worse than an open WiFi network, but that's not saying much at all.
A niche product for a niche market: for most folks wired ethernet or WiFi will do much better.
