I think SliTaz could make use of this as a package, it is a command-line file-sharing downloader. It downloads files from sites like Rapidshare and Mediafire from the command-line.
It has few dependencies, and it's certainly more SliTaz-like than jDownloader :)
I believe the right way to make this into a package, since it's updated frequently (yesterday for example), is to make one that dynamically grabs the current git snapshot for the project and make install
s it.

(Also, this is another one, that has a GUI: http://www.tucaneando.com/index.html and this one too: http://pyload.org/ )
