Once again, the arduino can be used to interface with several spi devices (I
usually just use software bit banging for something low speed like this). It
can also be used for your digital IO needs. It is also very easy to
interface with the arduino because they have a USB to serial chip. Like

Forrester recently released a report on the Return on Investment (ROI) of
Google Apps. They found a 300% ROI, 38%-56% cost savings, and break-even
within 7 months. Over 3 million businesses have gone Google with Google Apps:
an online email calendar, and document program that's accessible from your
browser. Read the Forrester report: http://p.sf.net/sfu/googleapps-sfnew
