+1 with CORS enabled, this would be a great enhancement.

Hello, I already made this feature to send info about vector fields. It is used here: http://viewer.coaps.fsu.edu/GlobalHycom/mapviewer

If you are interested I would love to add it into master or a different fork.

Greetings @olmozavala! Would you still be willing to add this since you already have the code (sorry I have not been in touch sooner). We are working on getting a release out in the next today or tomorrow, but I don't anticipate too much time between this release and the next bugfix release, so we could definitely target that.

This would still be nice!

I'm doing some work on the ncwms (2.x) / TDS integration trying to wrap up remaining tasks for the TDS 5.0 release, and now have it setup to be able to return CoverageJSON from the wms service. Will be available in the next (and hopefully final) beta of TDS 5.
