Where would it exist ? Submit node, server node, mom node, all nodes ?
At least right now the information about the job does not exist on all 
nodes.

For monitoring of jobs, I use the scheduler's (Maui) view. Inside a 
job, I use the native mechanism of the MPI lib for launching (well, 
mpiexec for MPICH(2)) so no parsing of $PBS_NODEFILE. Then pbs_python 
for everything else. So I don't parse qstat/pbsnodes output and this 
means that I don't really miss a pbsfs...

I would understand better a need for it if this would become the 
standard way of providing information for Torque and even Torque tools 
like qstat and pbsnodes would take their information from it instead 
of querying the server. Or if it would become writable too as a way to 
interact with Torque...
