As Diego suggested, i checked AIDB site looking for existing software in this field.
There are 32 entries in the Workflow / Project Tracking section, but the info is a bit outdated and inaccurate.
Other than Alienbrain, I couldn´t find any program that fitted in the category.
Anyway, these 3 projects somehow called my attention:
Wiredrive Projects: A project-based client area used for reviewing and approving creative work and production documents.
PECS Tools Suite is a "Data Pipeline Management Solution": A software and hardware solution for the management of Motion Capture Studios, including Planning, Shooting, Team management of post production, Asset management and version control, Quality control and Delivery scheduling.
ReviewManager is an outsourced client-review tool
