Manufacturers have until 25 August to express interest in developing products for the proposed Project Canvas network-connected television platform, although they have yet to see the final set of technical documents, which will only be published when they are complete. Meanwhile, the project proposes to work with selected device partners that satisfy certain criteria. So much for creating an open technical specification. Project Canvas continues to prompt questions, concerns and complaints. If you have any comments on Project Canvas we would love to hear them.
