Hi Robert,

Great to hear that. Thanks for letting us know. Some comments inline.

Awesome! We worked hard to achieve that.

That's a tricky question. I have to say I just had a brief look at the
specs. My first question would be, can't you host it directly on
openannotation.org? I would also suggest to include some statements in your
spec saying that it is RECOMMENDED to host the context locally. I mean..
it's just a small file to put somewhere on a server. If "instance" documents
can be hosted, a context can for sure as well.

Hope this helps,
