I've tried to organize the 31 open EME bugs by status and/or topic. The
quoted text is from Paul's agenda for the April 1st telecon. I've removed a
few bugs that have since been closed and added the four new ones.

Mark, Adrian, Jerry, John, and me all have actions.


*Agenda item #1: Make a decision on Promises.*

> a) [NEW] Bug 25199 - EME should use Promises
>

>
> Status: Blocks: 17750 21798 24081 24216 24771.
>
I added an example of what the IDL might look like.


*Depend on the Promises decision and implementation (skip):*
These will resolved and/or need to be re-evaluated in light of the Promises
decision. If we choose to implement Promises, we should postpone discussion.
