#MediaWiki head, there are plenty opportunities to experiment with code being on the bleeding edge of its software development. The Narayam extension provides the input methods for languages where entering text can be an issue.
The current functionality is not yet ready for use on projects of the Wikimedia Foundation its looks have to be improved. It should for instance only show when there are input methods available for the selected language. The code has to make use of the ResourceLoader and there are probably things that need doing that I do not know yet.
Narayam is running already on translatewiki.net for one simple reason: we want it to be available to our localisers. We try to make it easy for our community to localise for their language. I understand that it should be possible to provide support for Kannada soon, there is a request for support for Sinhala and there is interest for an input method for Hebrew.
When the code is ready for prime time we expect that it will invigorate the projects that we know can do better and, in the mean time there is this.
