Sure. I can agree with this. I was talking about using sqlite as the  
sole database to use with Horde. Using something like sqlite for  
smaller subsystems makes much more sense than using it globally. E.g.,  
using it with Ansel, or Kronolith on a large install and having it  
churn through all the share, perms, tagger queries...

Agreed, and is one of the reasons I put so much effort into optimizing  
the tagger queries when testing with sqlite back in the day.
