Revision 100: /trunk/Naf - this is SVN repo, you could check it out with your favourite SVN client.
What you need is Media.php, ShellCmd.php and the Media folder. But, I need to inform you: since the thread has not been answered by anyone (therefore, I just thought that it is not of interest to community) - I didn't do much with this code - and it is currently in the same state that it used to be quite a long time ago. However, it could be useful - personally, I use it regardless of the fact that the architecture is imperfect in many aspects.
Ask questions here or by email (crocodile2u [at] yandex [dot] ru).
We could also discuss changes to architecture/featurelist - and implement them together: developer access to the repo is not a problem.
