I think you've pretty much covered the basics. I wonder if you want to
add a section at the end for getting info on remote machines ? At least
in the environment where I work, multiple people with multiple nodes,
often the problem is finding which node is available for running a job.
You can ssh <machine> ; top ( then repeat until you find a free machine )
You can ssh <machine> 'ps' etc. and put all this in a hacky script.
Or despite your disclaimer ...
ganglia daemon + server is becoming pretty common for monitoring
resources on multiple machines
