I would caution against changing the resource selection algorithm, 
that works by picking the first source that works, and doesn't ever 
switch once playback is in progress. In particular it doesn't ever 
look ahead or do any scoring to pick a best resource. (Note that this 
is different from how `picture` works, which also has `source` 
children.)

You will also have sites that don't use `source` elements but instead 
use `canPlayType` to set the source, and they would need some API to 
achieve the same thing.

I guess the problem is that we might be playing using MSE locally, but
 the remote isn't a browser at all and instead uses DASH or a plain 
URL? I suppose what is needed is more information about the remote in 
`RemotePlaybackAvailability` so that an alternative resource can be 
provided in `connect()`?

Whatever the API looks like, there will be fun questions like what to 
do if the remote resource has a different duration, or if it doesn't 
have the same set of tracks as the local one.
