And that's why many people hate this approach, as it forces people to 
use workarounds that make things even worse (tunneling everything 
through port 80 and POST comes to mind).

Indeed.

Can we please try to make process here? I have started a Wiki page at 
<https://wiki.mozilla.org/Plugins:SandboxedPlugins>, and I have also 
pointed out that HTML5 currently doesn't have a solid definition of 
"plugin" (see 
<http://lists.w3.org/Archives/Public/public-html/2010Jan/1275.html>) -- 
should I open a BugZilla issue for that?
