about the time i discovered your ShiftBrite devices i also discovered the BlinkM from sparkfun http://www.sparkfun.com/commerce/product_info.php?products_id=8579

I would like to know the advantages of yours over the sparkfun products... I already can see that yours are cheaper, but I'd like to know more. The sparkfun model seems to use the I2C protocol to talk to them, and from what i understand I@C allows each device to have a different "address" so in theory you could chain link them together, but have each one be a different color. I'm not sure if yours can do that or not. Please can you clarify and state each ones advantages and disadvantages....

is there a way to talk to your ShiftBrites over I2C with some sort of I2C converter?
