LanguageTool is a freely-licensed software package for checking spelling and grammar. We already have a testing server running in labs, but if we'll want to have true integration with the VisualEditor as it is used in Wikipedia, then we'll need to deploy it in the real Wikimedia cluster and not in labs. This will require some deployment preparation work:
- appropriate Debian packages
- configuration (puppet?..)
- upgrade procedures (LanguageTool developers release add new languages and release new versions all the time)
- (add as needed)
