Thought this was talking about "Command Line Interface" for a while. It in fact refers to Microsoft's "Common Language Infrastructure" (I thought this was CLR, or Common Language Runtime, but I’ve been out of the MSFT camp for a while). Anyway — what’s the difference between this and plugins/Java applets (anything that compiles to Java bytecode)/ActiveX? I suppose the biggest is that this proposes that 1) they have access to the DOM and 2) the browser implements the CLI environment.
