Well you will now find one at sameas.org:
http://www.sameas.org/?uri=http://dbpedia.org/resource/Berners-Lee
:-)

Great stuff Christian, would you like to give me some more sameAs data to
put there, or point me at where I can get the information?

By the way, I think there may be something slightly strange about the Linked
Data service, although it may be my lack of understanding of curl.
Anyway, will be useful to know if it is either.
Here goes.
curl -i -L -H "Accept: application/rdf+xml"
Gives

So the file that is finally delivered at

Seems to have a truncated Description or the # has caused a problem or
something.
