Why Homeplug is the Ultimate "Do-It-Yourself" Networking Technology

Barham Denniss makes some pretty good points for powerline LANs in general for Home Networking. He is also a HomePlug Fan when he correctly points out:

"HomePlug’s success has resulted in a blizzard of new and useful devices to take advantage of this cutting-edge technology. HomePlug hubs provide users with additional Ethernet ports, increasing the flexibility of the network, while further network expansion can be achieved with HomePlug wireless network extenders. Wireless network extenders piggy-back on the HomePlug network and send out a wireless signal, allowing devices with wireless network access to join the home network."

Not that Barham Denniss is confused who has "HomePlug-compatible devices". He lists:

• Actiontec Electronics
  OK
  
• Intellon
  No, they make HomePlug chips and not devices and have been bought by Atheros
  
• ST&T
  Sure
  
• Valence Semiconductor
  WTF?
  is an out-of-business maker of low power GPS chips. HAN Fan thinks Barham Denniss may have confused Valence Semiconductor with bankrupt powerline chip maker, DS2,  based in Valence, Spain.
