 From an upstream point of view, a host passthrough device pair (one 
object talking to /dev/i2c-N on the host, and one device per sensor 
talking to the other object) would be the best.

But if you can make I2C-over-parallel work, that would also be 
interesting.  And not much new code to write: all you need to parse the 
bitbanging I2C protocol is already in hw/i2c/bitbang_i2c.c.
