The suggestion about general web accessibility for the CoDeck interface came in the form of a rhetorical question -- "Why not make it as broadly accessible as possible?" In the Web School, of course, the answer is "No reason", since more users are always A Good Thing, but for CoDeck there were several good reasons for not simply turning their project into a Web video app.
First, the physicalization of the interface, using the gutted BetaMax deck, provides a communal affordance that it is impossible to replicate over the web. Second, since CoDeck serves a tight community, the density of communication among ITP video makers would be diluted by general accessibility. Third, having the video deck in the lounge makes it self-policing; the cohesion of the community keeps it largely free from abuse, whereas a generally accessible and password-free "upload and critique" video site would become a cesspool of porn within hours. Finally, serving a local community maximizes use of free bandwidth on the local network, enabling features that would saddle a public system with crippling costs.
