Hm, this doesn't solve the situation I was talking about, does it?

First, lots of computers are named localhost => not unique. And also if
two users on the same machine exchanges files, they can have the same
ID.

On the other hand, the generated ID is probably "unique enough" for this
to work. But it's not a very nice solution, in my opinion.

It's not impossible. It's possible that we happen to have the same id
for two different contacts in our e-d-s. The probability for it to
happen might be sufficently slim though.

That would work fine.

If we can check that the e-d-s instance is the same, we can sync
automatically, or if it's ldap, we can sync automatically always.
