Interesting scenario. I would say, our plugin does not currently support multiple redirects.
Wouldn't your multi-language site handle the page redirect for you?
Say, right now on your public home page, does it redirect to the correct language? Or only after the user chooses their language preference. Even if that is the case, once your members choose their language choice in their profile, shouldn't that redirect accordingly?
I'd love to change the world... but they won't give me the source code!
