+Below is the best-guess set of features that a rooter hardware device would
+include; this is a balance between good functionality, engineering feasibility,
+and cost at the 1k or 10k production batch size:
+
+ - Core
+    - ARM SoC, Freescale i.MX6
+    - Power management/regulator IC for SoC
+    - 512MB RAM
+    - No onboard FLASH, 8GB+ uSD card
+    - FRAM chip for routing table persistance
+ - WiFi
+    - full-size miniPCIe slot for off-the-shelf dual-band card
+ - 802.15.4 
+    - all-in-one stm32w chip, trace antenna (?)
+ - Ethernet
+    - GigE switch chip w/ PHY, 5 ports
+    - 4x LAN jacks with drivers for longer cable runs (w/ LEDs)
+    - 1x WAN jack
+ - Power
+    - 5/12v regulator, ~1amp
+    - Power connector
+    - Reverse voltage diode
+ - USB Host jack
+ - USB mini jack for UART/JTAG/Mass storage (how? USB2 hub?)
+ - Second SD or uSD connector (for expansion)
+ - status LEDs and drivers (PWM from SoC?)
+ - reset button
+ - power switch

+A device with the minimal hardware resources required to accomplish rooter
+goals, which could be implemented with as little engineering as possible. This
+would be very similar to the $90 open hardware BeagleBone development board;
+than design could be copied and extended.
+
+ - Core
+    - ARM SoC, probably BeagleBoard-compatible device
+    - power management/regulator IC for SoC
+    - 256MB RAM
+    - No onboard FLASH, 2GB+ uSD card
+ - WiFi
+    - Atheros ath5k-compatible WiFi bg baseband, radio
+    - Antenna connector
+    - regulator/powermanagement
+ - 802.15.4 
+    - all-in-one chip, trace antenna (?)
+ - Ethernet
+    - PHY IC
+    - Single 10/100mbps jack (w/ LEDs)
+    - Connectors with LEDs
+ - Power
+    - 5/12v regulator, ~1amp
+    - Power connector
+    - Reverse voltage diode
+ - Second SD or uSD connector (for expansion)
+ - status LEDs and drivers (PWM from SoC?)
+ - reset button
