I have  worked on some I2C drivers for Linux, as well as Arduino and 
searched for cheaper options countless times.  Yesterday's email made me 
to search again and really liked the way one of products I've mentioned 
was structured.

So I sat down and wrote an Arduino implementation of that specification 
just to see what the performance would be. You can find it at:

Best,
