By creating additional files wouldn't this further increase the
co-ordination required between the cluster nodes?
Whereas, by adding the data to the existing db file would mean that the
TDS would fall under the standard db 'coordination' activities.
Shouldn't those environments be considered when discussing/considering
new features? (They are a growing presence in IT shops)
