[Wikitech-l] How to create the article from the context of the originating Wiki in another one?

Hello,

I would like to ask for your advise on the solutions for the following issues.

I have two installations of Wiki for two different languages. It is absolutely independent Wikis (each has its own database, its directory of libraries, just like interwiki has).

Both of Wikis have the special page, which is used to create articles.

So, using this special page one can easily create an article in the Wiki, where this page is running (Article::newFromText, doEdit... and that's it). But how to create the article in the second Wiki?

To put in other words, all I want to do is to create the article from the context of the originating Wiki in another one. How can I do this in the best/correct way?

And as a follow-up, using wfLoadExtensionMessages I can load the messages for the current language, but can I load messages for the specific language? I.e. is there something like this: wfLoadExtensionMessages('plugin_name','language_code')?
