Namespace question

Hi, I do plan to write some haskell module specific to mandriva software or specification, for example a toolbox to parse the tree on mirror using media.cfg, or a tools to create rpm specfile following rpm scheme. Then I do plan to push thoses modules into hackage database, because I think it is the best way to have publicity, code review, bug report, etc... My question is related to namespace to use for such modules ? MDV.modules ? FOO.MDV.modules where FOO is an already existing namespace ? Also this question apply for more generic modules, eg which namespace should use an haskell RPM module ? Is it possible to create a new main namespace ? I think a FAQ is needed about this. Regards.
