New formula: spiped

Spiped is a utility for creating symmetrically encrypted and
authenticated pipes between socket addresses, so that one may connect
to one address (e.g., a UNIX socket on localhost) and transparently
have a connection established to another address (e.g., a UNIX socket
on a different system). This is similar to 'ssh -L' functionality, but
does not use SSH and requires a pre-shared symmetric key.
