I see now, the Masters monitor and arbitrate broadcasts.  It seems a bit tricky if the slave and master have a dialogue in which a delay might creep in.  Do all I2c slaves have the same addressing features? SPI, rather than I2C may have more problems with multiple slaves.  Some chips allow less address selection bits than others.  In general, I suspect the German technology is superior due to cultural pride in rigorous integration.  Phillips owns or owned the I2C format.  Part of the problem is that different end up chips can require either no initialization or a lot of initialization.  Reaching a parallel LCD is possible with an I2c I/o expander as a slave, but since the LCD requires its own initialization, one  amyneed to use an SX chip to create a customized slave or burden the master with the initialization process.
