Hoi,
I am the developer of the SignWriting MediaWiki Plugin. It enables a SignWriting viewer for MediaWiki software. It supports an International community and can be used for any sign language.
I just released a radically simplified version of the extension in Gerrit: 20 lines of PHP code and 50 lines of Javascript. https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/extensions/SignWritingMedi...
I am hoping someone can look over the code and point out any flaws.
I'm hoping it can be deployed on Incubator. I reopened a bug from long ago. https://bugzilla.wikimedia.org/show_bug.cgi?id=22216
The PHP code makes a call to the Resource Module to load "signwriting_thin.js" (3 KB file). The Javascript runs on the client side only if Formal SignWriting is detected on the page.
There shouldn't be any security problems for the server running this extension and there is a miniscule cost to the user's browser.
The MediaWiki extension is a wrapper for the SignWriting Thin Viewer available on http://SignPuddle.com
Thanks for your consideration, ∼Steve
