I might implement this eventually, but it is not specifically planned
for the next release.
One idea I've been considering is to implement this as a special case of
generic distributed processing support (which also does not exist yet).
The password hashes to crack would not need to be passed to the
individual "nodes" - instead, fork() would be used after initial
startup, resulting in memory savings. AF_INET sockets would be replaced
with pipes.
