You will need to install two or more language translations under bp-languages, but you NEVER NEED two buddypress installations.
Hi,
are there any reference-websites which are being run in 2 languages and can confirm that ONE BuddyPress-installation is sufficient to be able to run 2 languages ?
Many thanks,
Erich
There’s sticky post where everyone posts their urls. Go there, find yourself. If you are lucky, it won’t take time. 
@Erich73-
This is really a WPMU issue as the configuration files play a big role in getting multi-language support successfully setup.
Here are a few links that may help:

I would contact the people behind these projects and ask them if they’re working on BuddyPress integration.
Hi Jeff,
I do understand that the backbone of BuddyPress is WPMU.
As WPMU is managed / owned by Automattic, are they planning to make Multi-Language-Versions of WPMU a possibility ?
I do undrestand that this will take some time and therefore stopped the plan for running my website in 2 languages.
Many thanks,
Erich
Is it possible to share the LogIn/SignOn between 2 installations of WPMU/Buddypress?
In my case it wouldn’t be a problem if the websites (language1/language2) run each on a seperate installation of WPMU/Buddypress, because i want a strict seperation of the content regarding to its language (webiste1 = language1 = only content written in language1 / website2 = language 2 = only content written in language2).
The only concern that holds me back from this type of multi language setup is the that i want my user to be able to switch between the language1-website and language2-website with only one Login. So if the user is logged in on language1.website.com he should be able to switch to language2.website.com without any additional login (similar to the WPMU/MediaWiKi plugin > https://buddypress.org/forums/topic.php?id=2912).
Hi 21green,
I am looking for exactly the same thing.
Is there a developer out there who is able to achieve this ?
If yes, please contact me.

Hey Erich,
i know a developer who is able to achieve this. They wrote me a private message on the german buddypress forum as a reply to my post:
http://forum.wordpress-deutschland.org/buddypress/48801-buddypress-international-benutzerdatenbank-teilen.html
Maybe we could work somehow together to get something suitable for both of us. If you are interested in the developer write me a PM and i sent you the details (you can write in german if you want).
