Re: Charter Addition Proposal: "Trusted Code" for the Web

Although permissions have good uses they do not cover the entire spectrum of "system-level"
applications, at least not in a way that makes sense to me:

   http://www.sconnect.com/FAQ/#permissionrequest


The proposed scheme would rather enable high-level, service-oriented APIs that mediate access
to sensitive resources (like TLS client certification authentication already do).

Cheers,
Anders
