It's not at all clear to me how they're namespacing the invocation names.

Do they need to be unique across all skills?

Will there be a land-rush on all the good two and three work invocation names?

Do I manually select which skills will be enabled for my Echo, and only those invocation names will be accepted? What about conflicts?

it would be great if there was no namespacing, and multiple developers could register the same phrase. alexa/echo (what's this thing called?) should learn based on your usage what service you want to respond to a certain phrase.

For example, "turn on the lights" should work with whatever smart home hub alexa can find on it's wifi network, not just with whatever smart home company registers the phrase first.

That would be nice. I have LIFX bulbs and don't want to say Alexa, ask LIFX to turn on the lights.

I don't believe they will need to be unique. Users can browse for skills and manually enable them. I'm sure the app will alert you that there's a conflict when you attempt to enable a new skill that uses the same invocation name.
