Creative Commons Attribution License is for me good as any other that doesn't
limit flow of ideas.

I'm not developer, but I can try to break it, if possible, and than complain

But, one particular magnet client I can't recommend as my friends will not
check for version and source, for sure. What I actually do is to recommend
some subscription service like Rhapsody, not expensive and works for me, so
it may work for them too.

The specification is enough details.
The most of the people are using OS that drains pockets with add this, add

The http and ftp protocols are using built in error correction of TCP/IP and
that will fail sometimes, under circumstances that occur more often in
congestions like one on a release day.

Someone has to make them available, software maker or guys that create

It happens with software.

That is what is necessary to verify source of files.
