One service I tested returned a 403 when the Origin: header was
specified and the request originated from certain networks. I
contacted the team running the server and it sounded like this was a
bug that had already been fixed but not deployed. It does indicate
that other servers might mis-handle a CORS request.

In general evangelism is definitely needed to encourage popular media
hosting sites to support CORS. The WebGL working group is certainly
going to perform some outreach since that specification is most
directly impacted by these changes.
