The irony here, as I see it, is that an old, insecure feature
Microsoft built to try to beat Netscape is now being used by
Microsoft’s biggest current rival to patch IE. The upside for
developers is that Microsoft is going to have a hard time killing
Chrome Frame because it actually does the right thing — it’s
not hacking IE via undocumented APIs or unscrupulous haxie-like
code injection. They used Microsoft’s own well-documented and
fully supported platform to do this. Bravo indeed, Google.
