[wp-hackers] XML-based display and spoofing multisite

[William Davis]

I'm sorry I keep asking so many questions — if I'm annoying people  
please let me know. I have two this time.

My first question is if it's possible and advisable to spoof a  
multisite instance. The reason I'm asking is because caching plugins  
don't really work well with mobile sites — you can have caching bypass  
mobile devices, but then those devices aren't being served cached  
pages and it doesn't really work that well anyway. So what I'm  
thinking is to spoof a separate site — for example, m.example.com, and  
use the same database as the main site but serve a different theme,  
and that site would be cached as well.

The second question I have has to do with content delivery. I'm  
intrigued by NPR's open API (http://www.npr.org/blogs/inside/2008/09/creating_the_npr_api_why_did_w.html 
) and the diagram of how everything works (http://media.npr.org/images/api/architecture_diagram.jpg 
). I'm curious if anyone has ever tried this approach with WordPress —  
pretty much generating an xml file of everything in order to reduce  
strain on the database. It would be great for organizations that want  
to offer a robust API to others and/or have lots of delivery systems,  
such as different versions of the site, mobile, tablet apps, etc. What  
are everyone's thoughts on this sort of delivery system? I'm not  
advocating WordPress should adopt it, but I'm sure a plugin could be  
built to offer the functionality.
