We won't integrate Miro or the like as such, however...
There has been major work in the media subsystem below to eventually support feedable media from other sources such as Youtube and RSS. We still need to do the individual handlers and Orbiter code, but the infrastructure is in place. (Thank you aaron.b!)
So the end result will be a lot more integrated.
I do not think the intent of mentioning Miro was to indicate what it does.
I think the previous poster was alluding more to how Miro makes pushing donations to them easy so people are more apt to provide dollars to help fund hardware/development.
