I've been trying this and can't seem to duplicate it.  I have no problem
submitting and routing to remote servers without entries in server_priv/nodes.

The only requirement that I can find is that the submitting user and host must pass
userok() (add the submitting host to the receiver's /etc/hosts.equiv).

This is with torque-1.2.0p5-snap.1122411769 which is almost the same thing as
the 1.2.0p5 release.
