Thread:File sync with Commons; collaborative video editing (2)

Sorry, I rarely notice the Talk pages since there is no email notification.

Recent (>1.11?) versions of MediaWIki allow specifying arrays of foreign repositories. $wgForeignFileRepos has some documentation. You can make your local MediaWiki instance cache assets pulled from the remote repository for a specified period.

No, I don't know of a TeX2wiki online conversion tool.

Yes, the Kaltura collaborative video tool has been broken for the past month (WikiEducator status). Their bug tracker has been down all that time and they have not been responding to email. Unless you really need the collaborative feature of Kaltura, I would advise using one of the other video sources like Blip.tv (using Widget:Blip.tv) or uploading a movie in Ogg format to the MediaWiki Commons.
