I played with a USB<->8 x RS232 ports, it uses ftdi Linux driver, and
using null modem cables between this box and the cluster's nodes, along
with kermit, it is very efficient and robust (because very simple).

The main problem is the strange escape sequence you have to type to close
acces to the console redirection (leaving kermit is not as simple as
leaving telnet).
