I see that licenses and copyrights are still a difficult topic.
I’m personnally interested about it.
Do someone know a good book covering this topic without
being a bible ?

Nope! If you’re the copyright owner, you can sell proprietary licenses
at the same time as putting it out as GPL (which can be a valid
strategy, somewhat like Galaxy Gameworks is doing for SDL: you can pay
them to be liberated from the LGPL restrictions). One could have a
slightly improved version as the proprietary one, such as what Aladdin
used to do with Ghostscript (the GPL version was one behind, or
something like that).
You cannot revoke the By-CC license once it has been granted and replace it with a restrictive license.
That bit is true, though, if it’s been released with a certain
license, then that license works a bit like a two-way contract: as
long as the licensee keeps his part of the bargain, the licensor can’t
just “pull the rug out from under you”. But in the case of software,
you can definitely decide not to release new versions under the GPL,
say, you just can’t retroactively invalidate the license of the older
For By-CC, dual-licensing doesn’t make much sense though… Would
someone really pay money not to have to put the artist’s name in the
credits for their proprietary game?!?
