Thanks @Klaus for these snippets. I hope I don't need them ;-)

I think I don't need "shared subnets" in my case, for example.

I currently wait for the admin there to call me back, then we will try 
to test drive the relay setup. Currently ~85 leases in 4 subnets active, 
we'll see.

Unsure how the active leases will be handled, looking forward to see the 
behavior. Either it works or ... not.
