I, as an example of an "organization" as described above, have found these
things to be true.  The startup transient is high -- all those this-objects
and that-objects.  But once it's up and running, adding route relationships
is much easier using the route server than by adding BGP sessions.

Of course, I don't do anything complicated.  I understand that Sean and 
others have found that they need to do things with their route import and
export rules that the route servers don't have a way of expressing.  Perhaps
if I were running a net as large as Sean's I would have his troubles.
