In real experience, GConf's current network transparency is a disaster
not because of problems with the usage of CORBA, but because of the
ad-hoc nature of it. Just because workstation A and workstation B share 
the same home directory doesn't mean that workstation A can access
arbitrary (or any) network ports on workstation B. So, if the GConf
server happens to start up on workstation B because the user logged
in there first, then the user can't use GConf on workstation .

Solving this almost certainly requires going to a standard model 
where there is a dedicated "configuration server" for the workgroup;
then system administrators just have one more instance of a problem
they've solved dozens of time before.

For your current "blade" setup, the current GConf network transparency
may work, assuming that you trust the authentication  bits of ORBit.
But I doubt anybody is really happy with a random distribution of
gconfd's across the blades. And it isn't a general solution.

The D-BUS protocol isn't limited to local network connections, so a
D-BUS based protocol could certainly be reused for the central server
as well as a CORBA-based protocol, though perhaps neither is right.
