By default, standard universe will always open the following files 
locally on the execute node : /dev/null, /dev/zero, /dev/tcp, /dev/udp, 
/dev/icmp/, and /dev/ip.

So I think the current default behavior is what you were hoping for.

Note you can always explicitly tell Condor which files/paths to open 
locally (excute node) -vs- remotely (rpc back to the submit node) via 
options in the job classad.
