I'd like to commet ThomasV`s mail with the following points:
1. He is fully right that we have a language problem on the multi.source
2. to create new subdomains or to move some languages to other existing subdomains - that could be possible in some cases but not in every one. A subdomain needs not only two or three admins (at least), these admins must be long time admins as well. Languages that are served by one or two or three users now could turn to be dead subdomains very soon when these one or two or three users leave. We had this problem at the end of 2006 I think as there were created some 15 new subdomains.
3. to move the pages to a similar language - OK, but I guess we would have to discuss this with every such existing subdomain if they want this, and it could take some time. And, I am not sure if we would find this "similar language" for hosting in evry case. See Latvian that is a bit active in the last days - there is no similar language indeed.
We will have to discus this, I am sure, but in the meantime I would suggest to make some measures that would decreas the mentioned problems we have. For instance, we could eliminate the possibility to edit the main name space for IPs (only registered and authorised users could do). And, we could disable saving the pages without notice in the summary. New pages without a language category coould (could, not must) be deleted. Etc. etc.
