Done almost the same and called it BenBus. You can find it on my homepage at http://members.home.nl/bzijlstra
Somewhere at software/communication
The drillmachine (can also seen working on my homepage) has been made with this BenBus. Three steppermotorboards and one masterboard.
The firmware can be downloaded at www.circuitcellar.com/avr2006
