Loading this at the last minute means we need a bunch of special cases
in *every* command that needs routing, namesys, or even the public key.

If we ever have a case where we don't want to do this, we can add an option to
the (eventual) IPFS constructor. Handling this up-front is going to be
significantly less error prone.
