I can see someone making a very powerful open source WiFi router out of this. The Pi can run passively cooled unlike most Intel or AMD CPUs. You wouldn't be doing any DPI on the network traffic without slowing things down, but this thing with some networking hardware cards could become very interesting to many people.
The cost is too high because it's a niche product, of course, but such a board would be able to replace my home router/server quite capably with a good WiFi antenna and some ethernet ports.
