Thanks for both your responds.

It doesn't matter who. All I'm saying is, every restriction in a
license could scare off people from using work under the terms of that
license. Because of that, I believe it's interesting to see what could
be stripped from the license.

So essentially, the license is copyleft? Receiving a work that
includes a part released under a BSD license gives you the freedom to
redistribute that part?

I'm saying I want to obligate licensees to put a copyright notice, in
the documentation/license file along with a binary form. Simply
because contributers might want this. However, if the source code is
available "in the same way through the same place", that source code
will contain the copyright notice, too. In that case, I don't see the
point in putting the notice in the binary form as well. So in
conclusion, if the source code is available, I don't see why the
notice should be included in the binary form as well.

It's all my own work.
