+1 Rich's comments. We're interested in determining if Web Intents can implement the discovery requirements of existing protocols and devices. -Clarke On 11/10/11 8:27 AM, "Rich Tibbett" <richt@opera.com> wrote: >Hi Robin, all, > >Robin Berjon wrote: >> Hi all, >> >> here is a draft of the Intents joint Task Force charter for comments >>from WebApps and Device APIs.
