Welcome mcmorry, and thanks for making this module.
The following is maybe more directed to Ryan, but everyone it welcome to think about something.
What would it mean to implement this feature in the core? Would it be a lot of work to change the url mapping to support language name for a page? (edit: or even possible or making sense). I mean since you already have implemented the multilang fields, and given that there's a page title multilang field, I find it now strange that such a module is required to implement language urls which is a "must have" feature, regarding SEO, for a good multilanguage site.
Sorry to bring this up here a little late. I just am thinking about this subject a very long time and not only since PW, but haven't really payed attention to the multilang field and title and that something seems missing as the "last" brick for a on-one-page multillanguage solution (with speaking urls) out of the box. I'm ever since using separate language trees to build sites and it works very well and flexible, consistent, fast, not so polluted page edit mask, etc. so I'm more the one heading towards the concept of Olivers language module with synced, linked multitrees. But this is a different subject and maybe discussed in the other room.
