Thats correct. Prowler integrates different data sources (the resources), e.g.
databases, ejb servers, mailboxes, etc., via the so-called adapters in an
XML based repository. An adapter is responsable to convert data coming from
a resource to XML and if possible back. From this point of view Prowler acts
as a content feeder for portlets.
But you may use Prowler to store the customization descriptors in a transaction-safe
way. We've already thought about an integration of Jetspeed and Prowler. We'd
like to use Jetspeed (+ Turbine) as the web-(portal)-frontend and store all
user-related information (that includes customization) within Prowler.
Once the 'Portlet Cust.Description Provider Interface' is defined, it should be
easy to write a Prowler specific implementation.

Prowler is completely open source - Apache-like license.
