[Featureserver] Starter Question

[Bill Wordsworth]

Guys,
I store geodata in PostgreSQL serving it up with MapServer PHP
MapScript. From what I understand, I can set up my own private
FeatureServer and give a frontend to users allowing them to create,
edit and delete that geodata?

Can I *not* use OpenLayers/OpenStreetMap/Python for this job? I just
want to use FeatureServer to enable browser-based editing.
Cheers, Bill
