Sebastien,

ZCO and PCL do not have any data collection capability, you will need to
customize this for your application.  ZCO/PCL *do* have the capability
to work with many different data sources.  For example, see the examples
of deomo/zdata/cpoints and demo/zdata/zpoints in the demo application.
This would give you the option of storing user-defined features in a CSV
formatted file, or storing them in an external database.  If you use a
database, the PostGIS extension for PostgreSQL is excellent.  For points,
two columns in a MySQL table may suffice.  All you would need would be
several Python Scripts that implement ZCO's IDataStore interface.

I hope this helps.  I can't provide any better examples until I return to
my office next week.

cheers,
Sean
