Counting unique viewers?

I''m building an app where I''d like to track the number of
views of each
item, but I''d like to keep it from being spammable, so it counts unique
viewers rather than just the number of pageviews.

What''s a good way to go about this?  Should I build a database to
record
the IP addresses and save the request.remote_addr for each viewer in the
database, associated with each item?  And then check each viewer against
that item''s database of IPs to see if they''re unique before
incrementing
the view counter?

Are there other ways of doing it?

Thanks,
Jeff
