A user's XTool's page has a "Top edited pages" section which lists that user's nine most edited pages for each namespace, where "edited" is measured in edit counts. I find this to be a good mechanism for reviewing talkspace edits, but for mainspace I'd be equally or more interested in being able to see pages by authorship percentage. Is this technically feasible (or already available somehow)? Cheers!

Unfortunately this is not feasible :( The Authorship tool relies on an external service where we can't do arbitrary, large-scale queries like you suggest. Sorry!
Interesting reading—it prompted me to test the processing time of a heavily edited article like Che Guevara (22 sec) against that of a randomly selected article (2 sec), so I now better appreciate the complexity of the tool. I guess a top-authorship table would be feasible only if it were displaying cached data of authorship info that XTools was slowly scraping. It might be cool, but it'd full of holes and constantly out-of-date. Regardless, thanks for the response!
Is there any scope for implementing wikiwho in-house? I know there's been chatter about having something like the whocolor interface as a standard tool.
The source code is public, so it's really a matter of financing the servers. This will allow for other languages to be added too. There has been talk about this at WMF, but I don't know any specifics or a timeline.
That said Community Tech is building an official browser extension similar to WhoColor, using the existing WikiWho APIs. That should be released to the public very soon (maybe a month or so). More at meta:Community Tech/Who Wrote That tool.
An in-house hosting of wikiwho would be awesome indeed, the authorship tool is super useful!
