I agree - we discussed it some time ago with the same result. I think we 
can use XML file (it is suitable for such purposes), but we didn't made 
final decision about implementation.

For the purpose of external configuration sources (like LDAP or other 
DB) it will cache configuration as well, so in the case where it won't 
be possible to contact the configuration server the last successfully 
fetched configuration version could be used.
