well i dont think that there is an I2c pressur sensor, but i will look
either way it will be I2C, so knowing that would anyone like to write 
the drivers?  you could even make drivers for a pressure sensor and temp 
sensor on the same board, since they are both I2C. have it refresh them 
alternatly i guess. 
i think its a good project for someone. it would be very cool. 
if someone will write the driver please let me know.
thanks
