with i2c ram (or eeprom, if you're writing relatively rarely) that's
possible -- i don't know any i2c rams off the top of my head, though. but
in order to read from (or write to) the i2c memory, each pic has to be the
master for that instance. bus arbitration between different masters on i2c
is not according to some priority, it is according to whoever happens to be
first, or, if concurrent, to be high on sda when another master goes low
(the high one looses).
