Keywords - a "global", or framework defined mechanism, for keyword usage in content fields
Provide a mechanism that makes it simple for content authors to easily insert keywords into content (not just wysiwyg, but other field types too). Keywords could be exposed globally, eg $Member.Email, or an object might have a specific context for keywords.

How would this be designed to avoid the usual "Globals" problems like module one defining $Member.Email then module two over writing it?
