Okay that doesn't sound like it was very trustworthy... :-/

Especially this from the manpage:
       You must not specify clone sources unless you guarantee that these
       snapshots are exactly in the same state on both sides—both for the
       sender and the receiver.

I mean what should the user ever be able to guarantee... respectively
what's meant with above?

If the tools or any option combination thereof would allow one to
create corrupted send/received shapthots, then there's not much a user
can do.
If this sentence just means that the user mustn't have manually hacked
some UUIDs or so... well then I guess that's anyway clear and the
sentence is just confusing.

Since it seems to be a valuable feature with probably little chances to
get it working in the foreseeable future, I've added it as a feature
request to the long term records ;-)
