You need to study some more (European) Internet history.  Among
other things, you seem to overlook that the EUnet you know today, as
well as our infrastructure (in many ways similar to Ebone's), was a
result of political manouvering leading to us being kicked out of
Ebone at the time (6-7 years ago).  Then the really interesting hard
work started, building from the ground while Ebone had its US half
circuits paid by the NSF, and Rick Adams lent us a big helping hand
during those years.  (There is still much confusion caused by the
similar names of the two companies, but that's a different story.)

As you are probably aware, we have been on very friendly terms with
Ebone for several years now.
