As mentioned in the earlier thread, remoteness is not a reliable 
indicator of speed. You can have fast remote drives and slow local 
drives. Maybe in the days of 10Mbps ethernet it was still reasonable to 
assume that networked drives were slow, but with gigabit ethernet you'd 
be hard pressed to notice a performance difference between a networked 
and local drive.
