I'm a product engineer at System76, makers of fine Ubuntu computers:

I'm also the lead Novacut developer (think Google docs for video editing):

Novacut is built on Dmedia, a specialized distributed object store aimed at professional content creation:

Dmedia is the foundation of Novacut's real-time collaboration, and can likewise be the foundation for similar apps.
