Greg,
You can index a RV in the standard fashion - index on myexpression tag myexp .
Is the purpose to display data in different ways or to allow browsing/editing of data in different orders? The biggest benefit from a RV is the injection-proof automatic updates. If you're only displaying the data or editing data one row at a time in a separate form, you might consider SPT for the list and a separate RV to pull individual records for edits. That will make it easier to transfer to a web app as well, should that ever be contemplated in future.
HTH
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
