Is it possible to limit a user to a particular host, using the Resource Quota Configuration option in qmon for Sun Grid Engine?

I'm thinking of a line to the effect of:

{
...
limit users {john} to hostname=compute-1-1.local
}

The documentation mentions built in resource types: slots, arch, mem_total, num_proc, swap_total, and the ability to make custom types.

Details: SGE 6.1u5 on Rocks

update:

The above rule seems to be valid, since

• using an unknown hostname
• mangling the resource name 'hostname'

both cause errors
