yes. given that our OIDs are generated automatically and often, it makes 
no sense to regularly copy the whole tree to them.

the problem here is that we will still need to send them new versions 
whenever a new first level is added. I think manual duplication like 
that is just a recipe for failure. If there was a distributed resolution 
system (like the DNS), then we would not need to do copies and 
everything will be connected. Hence, I suggest we just have the entry of 
our root into their tree.

To me, what you just did with them is very good and enough: have them 
point to the root of our tree and let us handle the sub-tree.

my 2 cents,
