We are currently working on an internationalization/localization requirements document for Geeklog 2. The debate is that we would like to use PHP support for gettext() as a standard but we aren't sure how many of you out there (even you english-only folks) this will effect. How do you find out? Create a simple PHP page with [code]<?php phpinfo(); ?>[/code] in it and view it. Then do a search for gettext and see if you have it enabled. We'd prefer to use gettext() but if there are enough of you who's ISP doesn't support it we could build in support for the current translation method (with minor improvements).
