I was thinking the WURFL library would simply replace the browser.mappings and 
associated logic (step 3). It's quite comprehensive and can provide a lot of 
other device information, so it can just be a dependency and not one that needs 
to be maintained internally.

The rest would all stay the same. The user switch behaviour would possibly be a 
link/button maybe in the portal footer, which could update the UA mapping table 
appropriately.

cheers,
Steve
