Yes, in this case i have a single slave for all the masters.
If i want to gain it i have to use a SAN.
In every case i cannot use serial nullmodem cables anymore, and cross over 
cable shold be all connected to a switch.
But this is a single point of failure, may i use 2 switch and three ethernet 
card for every host?
