FacePro (http://www.facepro.net) has recently revamped their facial animation product offering with rates as low as $5/sec. To streamline the approval process, they've created REV, an online approval tool that uses FaceFX's rendering ability. Customers log into REV to view and comment on the animations that FacePro has worked on.
Definitely worth a look for developers that want to outsource tweaking FaceFX animations.
