I hope that FTP-master agrees. They've been okay with the ATI and nVidia drivers being shipped this way for a rather long time so there is hope.

This goes to the debates that have been had about GPLd libraries. where the dynamic linking happens on the user's machine. Might relate to Oracle v. Google and copyrighting interfaces.
