On-Demand OK, But How Demanding?

The BBC, ITV and Channel 4 are to launch a joint on-demand service, which will bring together hundreds of hours of television programmes in one place.

The service is set to go live in 2008 and will offer viewers access to current shows and archive material.

Plans will have to be approved by the BBC Trust and the other broadcasters' boards, and a name for the service will be unveiled ahead of its launch.

The three broadcasters currently offer their own separate on-demand services.

The BBC's iPlayer, ITV's catch-up service and Channel 4oD will continue to exist along the new online "aggregator", which will provide a complement to the established providers.

But that still doesn't make clear what the platform requirements will be for viewing this new super-duper on-demand service: who thinks it might be Windows only....?

Update: Ashley has more details, but doesn't answer my question, although to my eyes there's an implication that the new aggregator will be even less platform agnostic than iPlayer - which Ashley says *will* support GNU/Linux....
