Which package is this a branch of? Links would be useful so I can look 
at the implementation.

It should be somewhere content-type-agnostic if you want to use it for 
different content type systems. So not plone.app.contenttypes. And 
probably it should be in core so items with the interface applied 
directly don't break if some add-on is removed. CMFPlone or 
plone.app.content is probably a good place.

I found this at 
https://github.com/plone/plone.app.i18n/compare/master...plip-13091.

I like making the viewlet be a thin layer that uses an adapter to look 
up what languages are available. But I would organize things a bit 
differently. This needs to get rewritten so we aren't using the language 
tool. In that world we'll probably have a utility or adapter that 
provides methods similar to what the language tool provides currently 
(i.e. getLanguageBindings, getAvailableLanguageInformation, 
getSupportedLanguages). The "language" method of your "SelectorAdapter" 
probably belongs on that utility or adapter. And the "urlForLanguage" 
method probably belongs on an adapter of ITranslatable, since it has to 
do with a particular translatable item.

I found this work at 
https://github.com/plone/plone.app.controlpanel/compare/master...plip-13091-pam.

It would be nice to get the settings actually moved to 
plone.app.registry so we can get rid of the Language Tool.

Some of the negotiation settings are fairly advanced and won't work 
without more configuration outside Plone (i.e. serving languages based 
on subdomains). IMHO we should probably only include the common ones in 
the Language control panel, and document the rest as advanced options 
that can be found in the registry.

Seems to me like this should be part of the ITranslatable interface 
rather than inventing something else. If something is translatable, part 
of that is being able to get/set its current language.

What needs to happen here exactly?

We can just add this patch to CatalogTool in CMFPlone, so that it 
doesn't need to be patched anymore. Right?

The consensus on the framework team seems to be that we don't want to 
pick a particular multilingual add-on to be in core, but we want to make 
any changes we can to the core framework to make it easier to implement 
multilingual addons. That seems to be in line with what you're proposing 
above.
