I build mostly multi language application. To be honest, i think that the best of the both world will be to have a command that mean, load language file from standard language directory, AND load it from module language file.
I'll say i prefer having the language file at the same place, i don't want to restart stuff each time, if i mods validation language file, don't want to have to do it in each module etc. etc.
So to mem it's most important to load them from standard /application/language, but this will be a most if you can add the possibility to load them from module stuff.
From the size of your libs, i mean, having a switch say "Standard or Module" is not big deal i think.
see ya around
