People running their own instances can "upload" their individual database info (posts/comments/images/urls/etc) to a centralized server. The aggregated database would contain everything except the media files.
Pros:
Lots more info available, searching would be more exhaustive
Speed up ripping time for new users (already have URLs + albums without having to check every post/album)
Cons:
Solution will be complex (getting the data to the server routinely and in an efficient manner)
Potential for abuse (uploaders could send malicious or bogus content)
Implementing features that use the new data would be complicated
e.g. what happens when search finds a user in the aggregated db but not the local db?
