Codestyling-localization and multilingual content plugin

I have been using the codestyling-localization plugin for single user instance og WordPress, http://wordpress.org/extend/plugins/codestyling-localization/, but does anyone know if it is is compatible with WordPress MU 2.8.5.2. Another queston for experianced user about codestyling-localization. When *.mo and *.po files are ready in a language folder for a theme, how can I activate it?

I have also made an experiment with following multilingual content plugin in a single user Instance. Is any of it compatible with WordPress MU 2.8.5.2.?
