New Board to include:
LPC1768
Ethernet PHY: possibly supporting 100baseFX for a fiber-optic
at45 serial flash storage for the data logging storage
Max336: multiplexing and demuxing to allow 32 inputs that may be muxed into several different analog ranges.
Minimum two RS232 ports
minimum two RS485 ports
usb host controller
usb device controller
i2c interface brought to external pins
Device must host a webpage displaying the results of the data logging and be capable of updating the programing and configurations of the program over the Ethernet for remote upgrading.

Of course, as soon as you put your own LPC1768 on a board you have to deal with the problem of the MBED loader microcontroller and its connection to the LPC1768, which uses JTAG. I suppose you could make an MBED into an MBED interface by removing or disabling (by holding in reset, etc.) the LPC1768, and then connect the crippled MBED to your new board.
