I'm aware of that, but in this case SVN is the only option.

(Almost) perfect, thank you very much for the pointer. That describes my problem and a possible solution exactly.

Just making a tar.gz file out of checked-out sources and store that one. I'm sorry for the confusing description, but it doesn't really matter what I wanted to suggest since the other option to keep a repository checkout would be much better.
