Just as a point of clarification, there are two relatively distinct issues:

1) Existing IE versions don't support EOT files with OpenType CFF
contents (though the EOT format is agnostic as to CFF vs TT contents).

2) Windows default system rendering of OpenType CFF (and Type 1) fonts
is kinda stinky. Adobe worked long and hard with Microsoft to get
better rendering of OpenType CFF (even with ClearType support!) into
the WPF rasterizer, but AFAIK no browser is using that rasterizer.

Regards,
