Hi,
you could even run it without mknod from the source system (or target): exp xxx/xxx file=/dev/fd/1 volsize=0 | ssh target ". _setup_env_script; imp yyy/yyy /dev/fd/0"

/dev/fd/* are alias to a process' file descriptors, 0=STDIN, 1=STDOUT, etc.

I usually use this feature to transfer whole directory trees to other systems using tar.
