this is partly off-topic for this list, but the chip in the
picture of the above I/O controller is surprisingly similar to
the RTL8316 used on cheap 16-port switches, eg.
http://info.iet.unipi.it/~luigi/FreeBSD/edimax/
The chip is interesting because it decodes some UDP packets
to read/write an I2C EEPROM connected to its pins.
As shown in the above URL, is trivial to bring the control lines
out and so turn the 30$, 16 port switch into an ethernet-to-microcontroller
interface.
cheers
