I think its better for it to be global, since the typical use-case is 
for applications to be installed system-wide, and this way every user 
doesn't have to rebuild their own .db. You can think of it as being a 
Java equivalent to - most .so's are installed systemwide. 
Obviously, it also needs to be possible for users to use their own 
user-local .so's without having to register them in the .db. We havn't 
figured out exactly how that will work yet, but in the mean time, you 
can always override the location if neccessary.
