Andy's "remote file system run locally" just begs to be networked. I think they do the high speed serial IO with interrupts disabled and busy-polling. This works fine under msdos where IO is busy-wait and the networking and application are a single program. This method of IO would not be feasible under Minix with an interrupt driven serial driver. (80 microsecond interrupt response? not with minix)
