have thousands.  we're currently operating without auth (in part due
to configuration issues), so I don't know how well it will scale.  The
other aspect here is that in current configurations, every "run" has a
different machine configuration based on what you request from the job
scheduler and what you actually get.  We pretty much get different IP
addresses every time, with different front ends, different file
servers, etc. etc.
Again though - the idea is to use file systems more pervasively within
the applications as well -- so there may be multiple file servers per
node providing different services depending on workload needs at the
particular point of computation.  Read our MTAGS paper from last
year's supercomputing conference to get a bigger picture view on how
we view services coming, going, migrating, and adapting to changing
application usage and failure.
