If the U1 backend had no further dependencies on the U1 user daemon once 
it's got the oauth keys, it should be possible to provide an option to 
get keys either from environment variables or from a logged in gui 
session. That might work for both our use cases. Maybe default to the 
existing behavior so that existing users aren't confused but add an 
option to get keys from environment variables or some other method? I 
still think the bulk of the U1 backend would still need to be replaced 
so that it doesn't depend on the ubuntuone.couch module once it has the 
correct oauth keys.
