I am looking for a low-cost computer platform with discrete I/O capabilitiy and an Ethernet interface.
I need something in a box / mechanical enclosure ready to use in an industrial setting. The application is simple, not very processor intensive, process some inputs and transmit an IP / Ethernet packet; receive a packet and drive some outputs. Unfortunately it is very custom application. I either need a powerful scripting interface or the ability to write my own application. I would prefer not design any custom hardware or mechanicals as the quantity does not justify it. If I could find a platform to both develop and ship it in, that would be great.
Does anyone know of a product that would fit this niche? Any help is appreciated.

Hi, I was searching the same thing myself, as my budget is very low :(
I found the NSLU2 from linksys, which is an ideal platform.
It is an embedded linux system, with two USB2 ports, at 480mbs, and a 10/100 ethernet port, and a serial port (onboard 4 points connector). the processor is a IXP420 at 133MHz, which is basically an ARM Xscale compatible processor, with some extensions.. (can be overclocked to 266MHz , just by removing a resistor), and it runs LINUX. It as 32MB of sdram, and 8MB of flash in standard.
There are a lot of developpement around this little embedded system, search for "NSLU2 linux" on google ..
see this page --->
http://www.nslu2-linux.org/wiki/Main/HomePage
It is a network storage appliance basically, to share multiple USB2 hardrives via ethernet network.. it only cost around 80euros, (~ 90 USD)
at this price, it is unbeatable :)
The last linux kernel 2.6.11.2 and 2.6.12 are working on it, so every USB2 devices that kernel 2.6.12 supports, are working on it :)
Webcams, usb drive, DVB receiver, wifi cards, USB2 vga cards, and everything that linux kernel as driver for ...
If you nead more IO pins, you can juste add a homemade extension card, with a FT245 for example, or any USB to parallel IO usb chips...
like we say in French... "Que demande le peuple !!!"
