advanced properties configuration

I am going to use centipede (or is it going to be AntWorks? or ..) for a company build environment.
To support deployment and compilation of an application for development, test, acceptance testing, production we need more advanced property configuration than the XmlProperty task.

I while ago I read on TSS about JFig (
(http://www.theserverside.com/articles/article.jsp?l=JFig)
, which comes close to what I think is needed. Examples of other frameworks that do somewhat the same job are: jconfig (www.jconfig.org), apache commons configuration (http://jakarta.apache.org/commons/configuration/).

Do you think something like this would fit into our build system?
Anybody know other options?

TIA,
Michael
