Just recently read an article/discussion about OpenSSL vs GnuTSL  
(http://curl.hostingzero.com/legal/distro-dilemma.html), which made me  
read some parts of the GPL  
(http://www.fsf.org/licensing/licenses/gpl.html) more thoroughly and one  
thing that caught my eye was the end of section 3. Section 3 reads that if  
one distributes binaries in any form it should always come with the  
source. The end section says that if one makes the binaries available for  
download it suffices to make the sources available for download from the  
same place. Does this mean that we actually have to have a source repo or  
is it enough to point to where the user can get the code?

I guess you're saying that you want a version limit for dependencies so  
that one doesn't upgrade to far and break apps. This is possible with  
CheckDependencies, which André already said (but I thought I might clarify  
:) )
