Hi, i was thinking of getting XM4 verdex starter kit to have wifi, 10/100, and serial ports.  I need to do ADC too (10-12 sensors to scan)  4-20mA.  I guess i can either get remote i/0 and use the 10/100 or use ADC to read them.  verdex from what i understand dont have ADC (other that thru sound card or i2c), only gumstix.  has someone actaly devlopped ADC thru sound card or i2c.  Or maybe even better, something im not aware of??  thanks
