The purpose of the Dbus wrapper is not to act as a run around the GPL. 
The dbus wrapper is their to create a per session database thats fast 
and efficient memory wise (by using threads and threadpools). The fact 
that it also allows us to bypass restrictive licenses in this instance 
is a bonus :)

That said, DDS does not have to be part of Gnome. GConf may always 
default to a text file backend (IE lowest common denominator that works 
on all systems whether its NFS or a platform that does not support 
threads) and likwise a metadata server for Nautilus may well use text 
files by default for similiar reasons. However thanks to Dbus, DDS can 
reimplement any of these interfaces and so give the user or distro a 
choice of whether to use the text-based default or a faster DB based one.
